It must be slightly frustrating for Novak. Just the two breaks is slightly unusual and I think that's going to be on his mind now.

That's better from the Hungarian pulling back to deuce before firing a superb backhand beyond Novak Djokovic and following up with a wonderful passing forehand. Marton Fucsovics holds.

A break in the seventh game of the second set has put Joe Salisbury and Rajeev Ram in a good position to secure a place in the semi-finals of the men's doubles against Colombians Juan Sebastian Cabal and Robert Farah.

A powerful forehand across court from American Ram secured the break before Briton Salisbury followed it up with a hard-fought service game.

The pair bump fists in celebration.

Anything you can do... Fucsovics responds to Djokovic's volleying tactics by knocking down a backhand of his own in full flight. But he can't build on it and Djokovic has another chance to break.

Novak Djokovic sighs as a backhand of his own drifts long to wipe out the second break point. Deuce.

He comes flying forward to sweep away a forehand that Marton Fucsovics just about retrieves, only to find Djokovic ready to jab it away at the net. Break point number three..

An opening for Shapovalov as Khachanov scoops beyond the baseline for 15-30, but Shapovalov is visibly frustrated as a similar error costs him on the next point.

Khachanov then claims the set as Shapovalov sends wide.

We're back level!

A treat for the fans as Marton Fucsovics changes shirt at the end of the set - the bloke has more guns than the A-Team.

Well, I say treat. For most of us blokes here it is a crushing blow to our self-confidence.

He's cut like a waxwork model in a boutique shop window.

Bit of a confidence boost for Marton Fucsovics, those three games he won in a row towards the end of the first set, but he fizzes a backhand long from the baseline and looks a touch dejected.

The Hungarian then loops a forehand into the tape and it's two early break points for Novak Djokovic.

Novak Djokovic had his first set point after 22 minutes of this match. Now, 20 minutes later, he wins it with his sixth set point.

It had two story lines. The first five games, and the next four games, but ultimately it is about who wins the last point in the set - and Novak Djokovic did just that.

That's a superb drop shot from Denis Shapovalov. A really stunning shot in a contest dominated by huge hits.

That takes him to 40-0 - and he holds to love to make Khachanov serve for the second set.

And eventually the top seed gets over the line! Novak Djokovic takes the opening set in 42 minutes.

Not really sure what has got under Djokovic's skin here. The unforced errors have started flying off the Serb's racquet with more regularity.

This first set has turned into more of a tussle than Novak Djokovic was anticipating at 5-0 inside 20 minutes - he's now been out there more than twice as long but has another chance to wrap up the opening set after Marton Fucsovics jabs long. Two set points.

Shapovalov is in a decent position at 40-30 on the Khachanov serve as he looks to test the Russian's nerve, but the opportunity vanishes as he hammers long.

Khachanov is now one game from levelling this match up on Court One.

Ouch! Djokovic does the splits on the baseline, leading to a concerned look from chair Mohamed Lahyani.

"OK?"

Djokovic doesn't look up as he tries to compose himself. Eventually when he turns around he gives a gentle nod to the umpire.

You expect to see that sort of movement in the Olympics gymnastics, not Grand Slam tennis.

Bullet of a forehand winner from Marton Fucsovics, biding his time and hanging on in the rally before lashing one away from mid-court. He follows up with a huge serve that kicks out wide to hold.

Three games in a row for Fucsovics.

Denis Shapovalov keeps himself in contention in the second set by easing to a hold to back up his break.

Khachanov needs to retake control of things here...

A punchy ace from the Hungarian but he can't close out, though he does wrong-foot the top seed with a backhand that sends Novak Djokovic almost into the splits. Most of us mortals would not bend like that... deuce.

Djokovic has been giving that drop-shot a workout today. On the whole it has worked a treat.

We hear a couple of shouts of 'Idemo Nole!' before the set point - that's the Serbian equivalent of 'Come on Andy!'.
