Well this is five-star drama on Centre Court!
We are enjoying one of its greatest actors and the hard work of his competitor.

To be fair, Valerie, it is that he is able to do what he is doing at his age that makes Novak Djokovic all the more remarkable.

We are all so blessed to be able to watch another Wimbledon with the greatest player of all time competing. Even clearly a few years past his best, Novak can still compete against the top players! Remarkable.
Matt, Cornwall
Please stop going on about the age of the competitors, especially Djokovic. He is what he is. It is his tennis skills that matter.

Felix Auger-Aliassime is doing the right thing getting that Novak Djokovic forehand into play and taking it on.
However, it isn't easy playing touch shots in the tightest moments and Djokovic is executing some of them beautifully.
*Auger-Aliassime 6-7 (10-12) 6-3 3-6 7-6 (7-4) 4-5 Djokovic
Given a chance by a double-fault and an unforced error from Novak Djokovic, Felix Auger-Aliassime can't turn it into a break point.
Djokovic gets it to 30-30 with a nerveless drop shot and then producing a big first serve to get to game point.
And another. Djokovic is one game from the semis and the crowd roars.

I usually cheer for the underdog, but I honestly haven't got a clue who that is tonight. What a contest!

Hold on a moment, Felix Auger-Aliassime has a chance here.
0-30.

Felix Auger-Aliassime responds with a forehand whipped to Novak Djokovic's right for a winner.
A pump of the fist follows and he secures the hold with yet another ace out wide.

Or maybe it is going to be some sort of bullet backhand, like that one from Novak Djokovic, that gets it done?

Stunning.
Novak Djokovic gets it to 30-all with a magnificent backhand down the line.
That is vintage Djokovic. Nobody is getting anywhere near that.

Both players are doing a nice job of establishing a lead on their serves across the last four or five service games.
After Coco Gauff's match on Court One the other night, which finished at 22:58, there were some very nervous executives in the referee's office - but we should be alright for time here.

Those are two really beautiful advances from Novak Djokovic.
You just wonder if the back half of this fifth set is going to lie with who is prepared to come forward, potentially finish at net and take those chances.

There is a standing ovation - from nowhere - as the players head back out at the change of ends.
The crowd appreciate the brilliance we've seen from these two on Centre Court for the past four and a half hours.
Image source, Getty ImagesNovak Djokovic's longest ever Wimbledon match was against Rafael Nadal in the semi-finals in 2018.
It took a whopping five hours and 17 minutes and the match was played over two days.
The Serb led by two sets to one when play stopped at 23:02 BST on Friday but came back the next day to complete a 6-4 3-6 7-6 (11-9) 3-6 10-8 victory.
He then went on to beat Kevin Anderson in the final to chalk up his fourth Wimbledon singles title and 13th major title overall.
*Auger-Aliassime 6-7 (10-12) 6-3 3-6 7-6 (7-4) 3-4 Djokovic
Smart play from Novak Djokovic, making his younger opponent do some running with a drop shot that Felix Auger-Aliassime can just about get to.
He can't get the ball back in play, though, and grimaces as he walks back to his mark.
Djokovic is two games away from yet another Wimbledon semi-final.

You can see how Felix is just keeping calm and composed while Novak is blowing... I think it may be a Canadian win tonight!

Novak Djokovic drops his racquet in disbelief! Another line seasoned by Felix Auger-Aliassime.

Brilliant forehand cross from Felix Auger-Aliassime and Novak Djokovic just drops his racquet in disbelief.
The Canadian third seed gets to 40-15 before a double-fault offers Djokovic a glimmer of hope.
Nope. Big serve out wide and in behind it for a drop volley.

We don't have night sessions at Wimbledon, but we've certainly had some night matches.
This is another epic here on Centre Court.

A few on Centre Court have started to slink off but Cliff Richard is still there. He's sticking it out to the end, it seems.
