Five points in a row for Novak Djokovic, who seals the hold with an ace. Three break points? No sweat.

A calm leave from a jumping Novak Djokovic, withdrawing his raised racquet as he realises Stefanos Tsitsipas' lob is going long. Break point one - gone.

A big T serve is returned into the net. Break point two - gone.

When Stefanos Tsitsipas lost the French Open final in 2021, he probably figured he would be back in a handful of quarter-finals, semi-finals and finals of majors - but unfortunately for him it has actually gone the other way.

This year has especially been a very big struggle for him.

Now it's Novak Djokovic's turn for an uncomfortable service game, with a double fault and a couple of errors offering up 0-40.

He'd love an ace right now.

Another error from the racquet of Stefanos Tsitsipas. His groundstrokes haven't been as on song as his serves.

We say Novak Djokovic's serve has improved all the time, but it has just been marginal gains ever since he came out on tour.

It is such a weapon that serve.

In the previous game on Centre Court, one of Barbora Krejcikova's service games lasted more than 13 minutes.

Like Novak Djokovic, Stefanos Tsitsipas goes 0-15 down in his opening service but rattles off the next four points - including two aces - to hold.

Stefanos Tsitsipas' split with his dad is almost the best thing he has going for him right now.

He hasn't been playing well and his ranking has been going in the wrong direction, so he needed to make a big change. He made one in splitting ways with his dad.

Maybe that relaxes him a bit tonight because he doesn't have his dad in his corner for one of the first times in a decade. When you get to a point where you don't care, it frees you up - and I think he might be close to that point.

He needs to red line tonight, if he is going to win.

Novak Djokovic's serve hasn't taken long to warm up - an ace for 40-15 and a routine hold.

There’s a real buzz about Centre Court following the absorbing conclusion to the previous match between Barbora Krejcikova and Mirra Andreeva, England’s dramatic win at the World Cup, and the anticipation of the arrival of seven-time champion Novak Djokovic.

Djokovic and Stefanos Tsitsipas used to only cross paths in the latter stages of slams, with Djokovic winning both their meetings in major finals.

Tsitsipas has slipped down the rankings amid a struggle with injuries, so the crowd here should be in for a treat in this eye-catching second-round match-up.

Once again, Djokovic rocked up in his tailored blazer and the players were greeted with excited cheers as they walked out under the now closed roof.

Is Tsitsipas up to making this a late one? It’s time to find out.

After using his trademark violin celebration following his win over Wu Yibing, Novak Djokovic said he was expecting new choreography from his daughter.

Will we see it tonight? Thumbs up if you think Djokovic will win, thumbs down for Tsitsipas.

It is good to be tested unless you start spending too much time on the court and it starts affecting you later on in the tournament.

Of course Novak Djokovic is playing in this tournament because he is trying to win it, so it is tough to have multiple five-set matches.

BBC pundit Jamie Murray explains why Novak Djokovic's return of serve might be his biggest asset.

Stefanos Tsitsipas has made some attempts to try to fix his game because he has been plummeting for quite a while now. Bit-by-bit he is just going down the rankings, but the reality is he is a very good tennis player and a very good athlete. He is mentally pretty tough as well.

But he has a bad backhand that they haven't been able to fix. It is his main problem. He is making 30 unforced errors off his backhand regularly in matches yet he still wins, so that shows you how good he is.

In actual fact, I got so frustrated with it at one stage that I reached out to his manager and told him I know how to fix his backhand. I offered to go and fix it for free, but they came back and said he had a new coach. I can tell you one thing, they certainly haven't fixed his backhand yet.

It is so frustrating to me. Until he fixes his backhand, he isn't going anywhere.

Novak Djokovic is eyeing his first Wimbledon crown since 2022 as he bids for a record 25th Grand Slam singles title.

The 39-year-old has only lost once in the second round at SW19 - in 2008 - and has reached at least the quarter-finals on his past eight appearances.

He leads the head-to-head over Tsitsipas 12-2, including each of their past 11 meetings stretching back to 2019.

Greece's Stefanos Tsitsipas reached a career-high ranking of number three back in August 2021 - the same year he reached his maiden major final at the French Open.

He reached the final of the Australian Open two years later but hasn't advanced beyond the second round in the men's singles at a Grand Slam since the 2024 French Open.

His best performances at Wimbledon came in 2018 and 2023 when he reached the fourth round.

Seven-time champion Novak Djokovic will walk out on Centre Court shortly for his second-round meeting with Stefanos Tsitispas.

Djokovic, the seventh seed, was taken to four sets by Wu Yibing but came through 6-4 5-7 6-4 6-4.

Former world number three Tsitsipas, now down at 87th in the rankings, dropped just seven games in his straight-sets win over France's Hugo Gaston.

Women’s number one Aryna Sabalenka wants Wimbledon to follow the French Open’s lead and lift the ban on players’ dogs.

Sabalenka’s Cavalier King Charles Spaniel, Ash, was one of several dogs awarded accreditation at Roland Garros earlier this year but is having to watch Wimbledon from home due to the All England Club's strict no-dogs policy.

The only dogs permitted on site are service dogs and security/search dogs.

“I can understand why they made this decision. Obviously if the dog does something ‘wrong’ inside of this historical place, it’s probably going to take a bit of time to replace. They’re probably afraid of damages inside,” Sabalenka said.

“I have to say all of our dogs are very well-trained. They’re not going to do anything wrong inside of this beautiful building. We have to change that.

“It’s just like a little fluffy thing that always wants cuddles and love. Going to the park with him, walking around, is also like some sort of meditation for me.

“Wimbledon, please, I beg you, let the dogs inside!”

What do you think? Thumbs up for dogs, thumbs down for no dogs.
