Jannik Sinner seems absolutely destined to compete for his fifth Grand Slam title on Sunday. But as any veteran Wimbledon fan knows, anything can still happen.

For now, Sinner is firmly on course as he holds to 15.

Djokovic goes narrowly long, advantage Sinner. This is the Italian's 11th break point of the match, Djokovic is yet to force one.

Jannik Sinner covers the court at a frightening pace. A perfectly good drop shot from Djokovic is planted back past him by the Italian for another break point.

Djokovic saves it off the back of a terrific serve down the T, before another powerful serve earns him advantage.

But the Serb cannot convert, off balance on the baseline he slaps a forehand wide and spreads his arms in annoyance.

On we go...

Serving and volleying behind a second serve. This is one of the masters of the game just trying to find any way to stay in this match with Sinner.

If Novak Djokovic is not careful, this match could be over very quickly.

A slip on the baseline as he hits a backhand gives Sinner two break points to take early command of the third set.

Djokovic saves the first with bravery, a serve and volley on second serve. Then Sinner misses down the line - deuce.

Djokovic hasn't had a lot of opportunities on the Sinner serve. But he had a patchy set there where he missed three backhands he wouldn't normally miss then some forehands in that last game.

It is a long way back.

Fery has a solid couple of weeks, hasn't he? Starting the fortnight as world number 114 and as of Monday will officially be number 36 in the world, having won five rounds here as a wildcard.

He has introduced himself to a wider British public in a major, major way. He will have gained so much confidence from playing the way he has on these grass courts, and the way he has fought back from some pretty desperate situations in a couple of matches. His life will now change.

He will have to wait four weeks to use his new ranking in events, so the first one will be in Cincinnati and then he will have the US Open, where he won't have to go through qualifying this time. He'll be able to enter whatever tournaments he wants by the end of the year, which is a stark contrast to last year.

Now the world is his oyster.

Way too good from Jannik Sinner, pulling his opponent all over the court, Djokovic eventually gives, landing a two-handed shot in the net to give Sinner three set points.

Sinner only needs one with an unreturned serve. This is ominous tennis.

Novak Djokovic is doing all he can, he certainly is not playing particularly badly.

But he can only acknowledge with a thumbs up one of the finest lobs you will ever see from Sinner, zipped over the Serb's head and landed inside the baseline.

Djokovic holds to 15, but Sinner will serve for a 2-0 lead.

When your drop shot is so well executed that Novak Djokovic does not even take a single step towards it, you know you are doing something right.

Back to back aces from Sinner move him 40-0 up... three in a row! Ruthless.

That's 10 aces in the match from the Italian.

Very few players can do this to the great Novak Djokovic.

The 24-time major winner, while clearly not at his very top level, is being outplayed here against what is, essentially, a version of his younger self.

There are countless similarities in the respective styles of Djokovic and Jannik Sinner - but, right now, the Italian is executing them far better.

Just a beautiful game of tennis from Jannik Sinner, lovely drop shot.

There is a reason why he has only lost three matches all year.

Ooh, double fault for Novak Djokovic to open game seven of the second set. Can't afford many of those.

Jannik Sinner smells blood, stepping onto a weaker Djokovic second serve to set himself up with two break points.

Djokovic sees off the first with a much better second serve of 110mph followed by a brilliant winner picked up from near his feet... but a magnificent drop shot from Sinner seals the break!

John McEnroe was joined by Wimbledon finalist Linda Noskova on his BBC Radio 5 Live 6-Love-6 show last night.

Along with former British number one Tim Henman, former British number three Naomi Broady and commentator Kat Downes, they answered your calls live - and it was fun.

You can listen to a podcast of the episode here.

Now then. Novak Djokovic has upped the tempo here, and goes 0-30 up on Sinner's serve.

Sinner pulls a point back with a powerful serve and volley, then is grateful to see Djokovic send a backhand down the line narrowly the wrong side of the chalk.

Massive ace from Sinner, 121mph out wide! 40-30.

And when Djokovic goes long, his faintest hint of a break chance is gone.

The crowd will want this to go the distance.

It will only do Wimbledon justice for this to go to five sets.

Novak Djokovic needs to shorten the points because the more shots Jannik Sinner has to hit, the more Novak has to deal with his power.
