Auger-Aliassime wins the second set tie-break to level the match. From 6-6 Davidovich puts a terrible forehand into the net then a backhand long in the following point to throw away the tie-break. The trainer is on to see to Davidovich’s left ankle.

Davidovich looks to be struggling with an ankle injury. He crouches down in pain but pulls himself together and begins peppering Auger-Aliassime’s backhand again. He clearly sees a weakness there. It’s 5-5 in the tie-break.

Back on Centre Court and Osaka is showing her mettle. Having held her first service game she forces a couple of crucial errors from Sabalenka before unleashing a fine winner to snare the first break. 2-1 to the Japanese.

Davidovich v Auger-Aliassime goes to a second set tie-break. The Spaniard proved too good in the first one and if he prevails again this could be curtains for the No 3 seed.

Sabalenka starts in grand style, racing through a dominant service game to win it to love. A perfect start from the world No 1. How will Osaka react?

Thank you Sarah, and what a game for me to land on. Sabalenka v Osaka in the warm evening sun is what Wimbledon Sundays were made for. Let’s hope they serve up a cracker.

Much like I can imagine Djokovic and Safiullin are going right now, I am going for a lie down after that four-set cracker. I will be back a little later but for now Rob Bleaney will take you through the next hour. Sabalenka and Sabalenka are now out on centre court with this battle set to get underway shortly.

There will be another huge match today on court one with Coco Gauff taking on Belinda Bencic but that will take place once Davidovich v Auger-Aliassime wraps up.

Let’s have a look at the other scores around the tournament now. As I said earlier, Davidovich won the first set against Auger-Aliassime 7-6 and the two are locked at 3-3 in the second right now. Hurkacz is beating Struff 4-2 in their first set on court two.

Next on centre court will be Aryna Sabalenka against Naomi Osaka. That one is due to start at 5.20pm BST but I have a feeling it will be more like 5.30pm.

Djokovic says: “Another hard fourth win. Roman started very well, very aggressive. He is a very solid player, I respect him a lot. I wish him good luck for the rest of the season, he should be proud of his performance today.

“Survive to thrive is how I feel. Hopefully the thriving part is coming. The outbursts, the meltdowns I had a few today. I apologise.”

You have to give props to the qualifier Safiullin too. He really battled to win that third set and just some lack of clinicism in certain moments meant he couldn’t capitalise on momentum. He applauds the crowd as he heads off of court and Djokovic will speak next.

This win means Djokovic will play in his 66th major quarter-final. Unbelievable.

Safiullin 6-7 (6-8), 3-6, 6-3, 3-5 Djokovic* (*denotes next server)

Djokovic could win this match now if he breaks Safiullin and at 15-15 he hits a great backhand to go within two points. But the Serb hits the net and a wild hit sees Safiullin 40-30 up. A Djokovic-esque hit sends the game to deuce with the seventh seed determined to see this match out now.

Advantage goes the way of the Russian and an ace sees him hold.

Safiullin* 6-7 (6-8), 3-6, 6-3, 2-5 Djokovic (*denotes next server)

Safiullin can’t return the first serve and then Djokovic sends a ball long to the shake of his head at 15-15. The Serbian is really not happy out on centre court, despite being close to wrapping up this match. A great backhand and a rogue return from Safiullin puts Djokovic a point away from holding and he does just that.

Safiullin 6-7 (6-8), 3-6, 6-3, 2-4 Djokovic* (*denotes next server)

A forehand winner from Safiullin starts this game and a nice drop shot follows it up. Another drop shot puts Safiullin 40-0 up, he has played some great tennis this afternoon, but a rapid return from Djokovic gets him on the board. But the underdog wraps it up.

Hubert Hurkacz and Jan-Lennard Struff has begun on court two with the Polish star 1-0 up in the first set.

Safiullin* 6-7 (6-8), 3-6, 6-3, 1-4 Djokovic (*denotes next server)

Djokovic now just needs to hold each service game and he will sew up this match. He, of course, will also aim to break Safiullin but holding is all he needs to do. A wild shot at the end of a long rally though brings Safiullin into this game at 15-15 but a sliced backhand puts the seventh seed back in front. Djokovic is on the edge of holding with a long shot from the underdog but Safiullin hits a shot that clips the net and Djokovic can’t see it over on his return. But he managed to hold eventually.

Davidovich has won the opening set against Auger-Aliassime in a 7-6 (7-4) tie break win. The matches at Wimbledon this year are anything but easy.

Safiullin 6-7 (6-8), 3-6, 6-3, 1-3 Djokovic* (*denotes next server)

Safiullin needs to win this game to get some confidence back in his game and Djoko gifts him the opening two points. A deft backhand earns Djokovic a point back and a mistimed drop shot from Safiullin puts it at 30-30. Djokovic hits the net and a forehand winner sees Safiullin win his first game of this set.

Safiullin* 6-7 (6-8), 3-6, 6-3, 0-3 Djokovic (*denotes next server)

Something has clicked for Djokovic and he is back to his best in this fourth. A drop shot, well orchestrated point, Safiullin hitting the net puts Djokovic 40-0 up but a mistimed hit gets Safiullin his fourth point of this set. The qualifier gets to 30 but Djokovic secures his hold.

Safiullin 6-7 (6-8), 3-6, 6-3, 0-2 Djokovic* (*denotes next server)

Safiullin hits the net and a lovely cross court forehand puts Djokovic 30-0 up. A mishit from Safiullin and a lovely forehand sees him break.

Safiullin* 6-7 (6-8), 3-6, 6-3, 0-1 Djokovic (*denotes next server)

Safiullin has been re-energised since he received that treatment to his hip and it has carried on into this fourth set as he is 30-0 up on Djokovic’s serve. A ace puts the Serbian on the board and a great drop shot puts it to 30-30. Safiullin has break point as Djoko can’t return a chipped shot but he cannot execute and so we go to deuce.

He staves off the threat and Djokovic holds.

Safiullin 6-7 (6-8), 3-6, 6-3 Djokovic* (*denotes next server)

All Safiullin needs to do is hold. He is yet to win a set against Djokovic across the four meetings the pair have had. He gets to 30-15 and a long shot from Djoko puts him within a point of pushing this to a fourth set. He does it, huge. What resilience.

Safiullin* 6-7 (6-8), 3-6, 5-3 Djokovic (*denotes next server)

Safiullin was in this exact position in the first set but he did not capitalise and Djokovic battled back to win it in a tie break. The Serbian will force him to serve for the set as he wins the game to hold.

Muchová was 4-1 up in the deciding third set against Krejčíková but it is now at 4-2.

Safiullin 6-7 (6-8), 3-6, 5-2 Djokovic* (*denotes next server)

Can Safiullin make this one count? He gets to 30-0 well and Djokovic’s frustration is clear as a missed drop shot put him 40-0 down. A great forehand sees Safiullin hold.

Djokovic whacks a ball in frustration and he gets booed for the action. He has to be careful, the umpire has warned him already about his behaviour.

Safiullin* 6-7 (6-8), 3-6, 4-2 Djokovic (*denotes next server)

Safiullin is okay to keep going, hopefully his hip isn’t giving him too much discomfort. It doesn’t seem to be as he expertly moves Djokovic around the court to win the first point. Again, a delightful backhand puts the underdog 30-0 up and Djokovic uncharacteristically puts it out of play. Safiullin now has three break points but an ace sees Djokovic defend the first and an incredible forehand defends the second. Safiullin smacks the net to send the game to deuce.

The Russian changes direction on a rally and it secures him advantage but some lovely work close to the net sees Djokovic defend yet another break point. Back and forth we go but eventually he breaks him, on the seventh time of asking.

Safiullin is still on the floor receiving treatment, Djokovic is keeping himself warmed up. This is so tough to watch with the Russian overcoming injury issues to play so well at this tournament but he currently has a towel over his face in discomfort. He gets back to his feet and I think he will be okay to continue.

While he receives some treatment let’s get some score updates from across the tournament. Auger-Aliassime and Davidovich are at 2-2 in the first set, while Muchová and Krejčíková are 1-1 in their deciding third.

Safiullin has called the trainer out and he is having a discussion with him now. The trainer puts a towel on the floor and Safiullin lays down with the trainer looking at his hip. His long-term injury was with a hip issue, let’s hope he is okay.

Safiullin 6-7 (6-8), 3-6, 3-2 Djokovic* (*denotes next server)

It felt like it was going to be a quick service game but Djokovic has forced this to deuce, he wants this match wrapped up. An ace give Safiullin advantage and a long shot from Djoko sees him hold.

Felix Auger-Aliassime is underway against Alejandro Davidovich with the game on court 1 currently at 1-1.

Safiullin* 6-7 (6-8), 3-6, 2-2 Djokovic (*denotes next server)

Safiullin had chances in the first set to take it and in this third he had the opportunity to go 3-0 up but both times he hasn’t taken it and a frustrated Djokovic looks likely to win a straight sets match now. The Serbian quickly secures 40-0 and a lovely move to the net secures hold.

Impressively Krejčíková has managed to come from 5-2 down in the second set to take it 7-5 to push the match against Muchová to a deciding third set. Absolute massive from the former Wimbledon champion.

Safiullin 6-7 (6-8), 3-6, 2-1 Djokovic* (*denotes next server)

Djokovic shouts in frustration and he gets a warning from the umpire. Safiullin’s issue is he can’t capitalise when he is on top, this would be the perfect opportunity to put more pressure on Djokovic but the first point sees him force the ball out of play. He does the exact same thing on the next two balls and Djoko now has break point.

He doesn’t take it on the first opportunity but he has two more attempts and he take it on the second.

Safiullin* 6-7 (6-8), 3-6, 2-0 Djokovic (*denotes next server)

A frustrated groan meets the first point of this game as Djokovic hits the net, the seven-time winner has clearly got into his groove in this match but he still doesn’t seem 100% comfortable. A rapid ball into the net puts it to 15-15 but a lovely cutting shot put Safiullin ahead. He can’t keep the pressure up with a long ball but then Djoko spins with his hands in the air as he gifts Safiullin break point.

Djokovic makes an error and Safiullin breaks, that was all the Serb’s fault.

Safiullin 6-7 (6-8), 3-6, 1-0 Djokovic* (*denotes next server)

Safiullin has all the pressure on his shoulders as he must win this set to stay in Wimbledon. He makes Djokovic wait to get this third set underway with around seven minutes the gap between the last point and the start of the third. The Russian wins the first point but fumbles the second. A drop shot puts him ahead again and a fabulous forehand winner gets the game to 40-15. A greatly played forehand sees him hold.

Karolína Muchová is 5-4 up in the second set but Barbora Krejčíková has done well to keep her hopes alive. She lost the first set 7-5 and went 5-2 down in the second but she is fighting on court two to push it to a decider.

Safiullin is walking off of the court for this break between sets. He has a huge mountain to climb if he is to win this match.

Safiullin* 6-7 (6-8), 3-6 Djokovic (*denotes next server)

Djokovic needs four points to seal this second set and easily wins the first. He misjudges his volley to put the ball out but an ace gives him his second point. Djoko is not doing this cleanly as another wry hit puts the game 30-30 but a drop shot gives him set point which he secures.

Safiullin 6-7 (6-8), 3-5 Djokovic* (*denotes next server

Can the qualifier hold on and make Djokovic serve for the second set? He can. A well controlled game keeps him in the set but now he must break Djokovic or the seven-time winner will be two sets up.

Karolína Muchová and Barbora Krejčíková are into their second set after the latter won the first 7-5. Muchová is currently 5-2 up in the second.

Safiullin* 6-7 (6-8), 2-5 Djokovic (*denotes next server)

Djokovic seeks to compound that break with a hold of serve and he races to a 40-0 lead but a lightly placed drop shot from Safiullin halts a perfect game for the Serbian. But Djoko manages to hold.

Safiullin 6-7 (6-8), 2-4 Djokovic* (*denotes next server)

Now, could this be where the second set changes? A forehand shot goes out from Safiullin and a lucky edge close to the net puts Djokovic 30-0 up. Yet some epic close action this time sees Safiullin have cat-like reflexes to get himself on the board in his service game. He follows it up with a loose ball and Djoko has break point. The Serb can’t execute the first but he has another opportunity yet he slips again and the game is at deuce.

Advantage goes Djoko’s way for another break point but he hits the net and so back to 40-40 it is. Eventually the star gets it over the line and the second set is in his control.

Safiullin* 6-7 (6-8), 2-3 Djokovic (*denotes next server)

In this second set both players have looked quite comfortable on their own serve with no threat of a break yet. This game is no different with Djokovic controlling the game well until Safiullin hits a smash ball to get on the board at 30-15. Safiullin puts the ball out next but Djoko gestures in frustration as he slips a few times during that rally but he holds.

Safiullin 6-7 (6-8), 2-2 Djokovic* (*denotes next server)

Both players are using the majority of the allocated time to serve, the clock ticks down to around four or five seconds before they both eventually hit it. This time Safiullin is serving but a double fault lets Djokovic into the game and a delightful forehand winner puts the Russian 30-15 up. Djoko puts another ball out of play and he hits the net for Safiullin to hold.

Pegula has quickly got to a 3-0 lead in the deciding third set against Jovic. The teenager started well against her fellow American but has dropped off since.

Safiullin* 6-7 (6-8), 1-2 Djokovic (*denotes next server)

A well-timed drop shot and a light forehand puts Djoko 30-0 up. Two unreturnable serve comes next and the Serb holds.

Safiullin 6-7 (6-8), 1-1 Djokovic* (*denotes next server)

Djokovic’s cap is back on as Safiullin serve and the Russian races to a 40-0 lead. He forces Djokovic to move toward the net and he orchestrates the point well to hold.

Safiullin* 6-7 (6-8), 0-1 Djokovic (*denotes next server)

This second set to underway around six minutes after Djokovic wrapped up the first. Safiullin has started well, the impact of losing the first not clear from his form. A nice drop shot puts him 15-0 up on Djokovic’s serve but he then smacks the net and then it is out to give the Serb a 30-15 lead. A net-clipped shot bounces over and Djokovic has the opportunity to hold and a lovely read of play sees him tap a shot to do just that.

Djokovic has gone into the changing rooms in this break between sets, while Safiullin has remained out on court under an umbrella.

Gavriella Epstein-Lightman has emailed:

Safiullin reached the quarter finals of Wimbledon in 2023, losing in four sets to Jannik Sinner. I was there and witnessed Safiullin’s crackling pace firsthand. Three years later, he’s troubling Djokovic in a fourth round match that he scarcely believed he’d be able to reach, given his injury woes. Incredible stuff.

His emotion in his pre-match interview about the support from his wife and overcoming injury was so moving. Safiullin is playing so well and probably better than most would have thought, if he can keep that up and get a set this could open up.

Pegula has won the second set 6-3 against Jovic, who took the first 6-4. The deciding third set is coming up soon.

Safiullin will be disappointed he didn’t get that first set under his belt. He served for the set but Djokovic managed to break and from there it felt like the seven-time winner would take the first. Safiullin needs to quickly put that behind him and move forward.

Safiullin 6-7 (6-8) Djokovic

A smash wins Safiullin his first point of the tie break after Djoko secured the first. There is a fist pump from the qualifier as he sends a ball rocketing past Djokovic to go ahead. Safiullin’s forehand winner puts him 3-1 up, remember he only needs to get to seven to win the tie break. Djoko creeps back into the battle with Safiullin sending a shot long and a lovely drop shot puts it at 3-3.

The Serb goes ahead with a drop shot going awry for Safiullin and another forehand is out from the Russian. But Djokovic isn’t clinical with his lead just 5-4 now. Safiullin makes another error and Djokovic now has two set points, surely he will make this count? He doesn’t with the first with an expert rally well worked by Safiullin and then he hits the net! Wow.

The drop shot was the right decision there from Safiullin but the execution isn’t there and so Djokovic has another set point. This time he wraps it up.

Safiullin* 6-6 Djokovic (*denotes next server)

Djokovic looks like he will be sending this to a tie break as he gets quickly to 40-0 and there it is, a huge task for Safiullin to beat the seventh seed in a tie break.

There is a huge battle on court 1 as Pegula is 4-2 up in the second but she was 4-1.

Safiullin 6-5 Djokovic* (*denotes next server)

A great rally ends with a drop shot bouncing just out and Safiullin races to a 40-0 lead with Djokovic forced to send other shots out and he then holds.

Safiullin* 5-5 Djokovic (*denotes next server)

That break of serve is exactly what Djokovic needed and he looks much more himself in this service game. Safiullin has also out of sorts, he has put so many shots long and he just needs to calm himself. Djokovic is at 40-0 but hits the net before sewing up the game.

Safiullin 5-4 Djokovic* (*denotes next server)

Djokovic perfetly weights a return for Safiullin to hit the net. There is quite the Djokovic fan club on centre club, they have been in full voice since the Serb’s form has dropped. Djoko bends and shouts in frustration as he hits the net himself but a rogue drop shot give Djokovic break point and he wins it on the first time of asking. Safiullin has wasted a chance to take the first set.

Safiullin* 5-3 Djokovic (*denotes next server)

Djokovic has taken off his cap for his latest service game, one he must hold to keep himself in this first set. Safiullin is in full control of each point as he sends Djokovic across the court at 15-15 and the Serb sends the ball out next. The seven-time Wimbledon winner is not currently in the top form we usually see him in but gets a forehand winner to send it to 30-30. Safiullin is on the precipice of break and set point as Djoko hits the net but it is sent to deuce with an ace.

The Russian gets set and break point again, can he confirm it this time? No he can’t as we go back to deuce. An ace give Sjoko advatange but after the longest rally of the game, a drop shot sends it back to deuce. Eventually Djoko manages to hold, Safiullin can now serve for the set though.

Pegula has gone 2-1 up against Jovic in the second set with a break but she did lose the first 6-4, the second is a must win for her. A huge performance so far by the 18-year-old.

Safiullin 5-2 Djokovic* (*denotes next server)

Safiullin hits the net but then he executes a delightful forehand. The pair exchange drop shots and then Safiullin lofts the ball which bounces just in, lovely tennis. A double fault puts the game at 30-30 but he marshals the next point well to go one point from holding. An ace does that for Safiullin and he is in the driving seat of this first set.

Safiullin* 4-2 Djokovic (*denotes next server)

Djokovic has put some eye drops in before this game, he has been struggling a bit in this match. He sends the ball long and then his first serve goes awry, he is again facing the sun where his game went off the rails slightly earlier. Safiullin’s smash gets him 30-0 up and a double fault gifts him break point. That was a fantastic point by Safiullin, wow. He sends Djokovic to both corners and the Serbian cannot return the second.

Safiullin 3-2 Djokovic* (*denotes next server)

Safiullin is going toe-to-toe with Djokovic in this match and it’s crucial because if the Serbian got on top it will surely be a done deal. Holding out as long as possible will be important and he gets to a 40-0 lead. Djokovic hits the net and Safiullin pokes ahead.

Safiullin* 2-2 Djokovic (*denotes next server)

Djokovic has the sun on his back now and races to a 40-0 lead in his service game. A rogue shot long from Safiullin sees Djoko hold in a quick game.

Pegula has lost the first set against teenager Jovic 6-4, action in the second about to get underway on court one.

Safiullin 2-1 Djokovic* (*denotes next server)

Djokovic does not look at all comfortable in the sun, the sweat is frustrating him. He remains in the sunshine as he receives serve from Safiullin but at 15-15 an ace puts the Russian 30-15 up and a beautiful drop shot puts him in touching distance on holding. That shot was that good that Djoko even appluaded it! He then easily holds.

Safiullin* 1-1 Djokovic (*denotes next server)

Safiullin who gets the first forehand winner of this second game. Interestingly Djoko keeps wiping his eyes with his shirt now he’s in the sun, he has a cap on but he looks frustrated with the sun. It has led to Safiullin getting two break points, an ace from Djokovic negotiates the first and the second but a wild shot gives the underdog advantage and he is broken.

Safiullin 0-1 Djokovic* (*denotes next server)

They are underway in the last 16 match on centre court and Safiullin wins the first point, he starts quite aggressively. The Serbian levels it before Safiullin hits a forehand winner but a great rally ends with Djokovic pushing his opponent left and right to get to 30-30. Safiullin hits the net to gift Djoko break point and an error sees him win it.

Pegula has got back to 3-3 in her match against Jovic, still in the first set on court one.

Djokovic and Safiullin have walked out onto centre court with their match coming up soon, we will bring you a game-by-game update from that while bringing you the big headlines from the other courts.

I know I am starting to get old because the commentators have just said that Jovic, who is playing Pegula on court one, is just 18-years-old. When she was born I was starting secondary school! Now she is 3-1 up against the fourth seed at Wimbledon.

The winner of who starts the singles competition first today is Jessica Pegula who is in action against Iva Jovic on court 1. Pegula is currently 2-0 down in the first set.

Brit Patten and Heliovaara have taken the deciding third set to a tie break against Pavlasek and Rikl. The pair won a tie break in their last match so can they do it again? They are currently drawing it 1-1.

I can’t wait to see Naomi Osaka’s look today, she has been using fashion to express herself and represent her heritage across all of the slams. So far at Wimbledon she has been wearing a white kimono and she told the BBC about it:

When I think about Wimbledon, it’s obviously the all white. There’s obviously the tradition of it all. In my head, when I think about that, I think about my cultures, my heritage, which is Japanese and Haitian.

Then, if I dive deeper into Japanese culture, I think about the most iconic silhouette, which for me is a kimono. You don’t have to see the colour of a kimono to know that it is a kimono.

I don’t know, I was thinking about my favourite movies also. I love Kill Bill. I remembered absolutely falling in love with Lucy Liu’s character.

She has an all-white kimono, and I remember thinking that was really cool. Then it just kind of went from there. It was like my interpretation of that, while also paying a lot of respect and love to Japan.

Osaka is scheduled to be on centre court against Aryna Sabalenka at 3.10pm BST.

Patten and Heliovaara are clinging on in this match. They were broken early in the third set by Pavlasek and Rikl but they have fought back to win a break themselves, they are currently 4-3 down but they are next to serve. A great match.

In the singles competition, Karolína Muchová and Barbora Krejčíková are scheduled to start the action on court 2 but that will happen after the men’s doubles match is wrapped up. So Novak Djokovic against Roman Safiullin could actually be the game that begins first on centre court. That match is scheduled for 1.30pm BST.

Elise Mertens is currently in action in the women’s doubles with Zhang Shuai as her partner. They lost the opening set 6-3 to Hsieh Su-wei and Wang Xinyu but they have pushed it to a deciding set after winning the second 6-4. Action in the third about to get underway.

Patten and Heliovaara have taken the second set 6-3 and so the match will be going to a deciding third set against Pavlasek and Rikl.

Staying on court 2, Patten and his men’s doubles partner Harri Heliovaara are a set down after losing the opener 7-2 to Adam Pavlasek and Patrik Rikl but they are winning the second 5-2.

A fan is having an issue on court 2, there is a pause in the men’s doubles match. Brit Henry Patten spotted the lady was having some trouble and stopped play to make sure she got the attention she needs. The commentators have confirmed she is okay and is helped out by security.
