The Centre Court crowd can’t help but gasp mid-rally as Novak Djokovic and Stefanos Tsitsipas engage in an absorbing exchange, the Greek in particular slicing his shots so low that many can’t believe they have managed to escape interference from the net cord.

Tsitsipas crouched to the ground after faltering on a trademark backhand down the line, and a huge opportunity to get back into this set evaporates before his eyes.

It hasn’t taken the players long to get the crowd hooked on this.

Stefanos Tsitsipas nails a few first serves to race through his latest hold.

Oh, Stefanos Tsitsipas has just pulled it wide! What a rally. A good use of the slice though, you feel that will be important for him to utilise today.

Novak Djokovic has won five straight points. You get a feeling he is already in command of this second-round match.

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.

Locked in a baseline exchange, Tsitsipas pulls Djokovic into the net with a sliced backhand but drags his forehand pass into the tramlines. Break point three - 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.

Novak Djokovic makes the early break.

At 15-all, Stefanos Tsitsipas and Novak Djokovic trade baseline blows in consecutive rallies and Djokovic comes up trumps on both occasions, aided by long strokes from his opponent.

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.

Novak Djokovic and Stefanos Tsitsipas appear to be competing for the shortest service game.

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.
