Huge support from the crowd as Norrie returns to the court, looking to bounce back from that huge setback.

An immediate response here would really get Centre Court going.

Ah. It's long from Norrie and Djokovic has the early break.

Uh oh. Djokovic will have a shot at a break point at the start of this fourth set as Norrie misses with a backhand.

A delightful backhand from Norrie draws an error from Djokovic for game point, but Norrie swats into the net. Deuce.

The crowd rally behind Norrie once more.

Norrie has Centre Court cheering again as he glides a backhand drop shot over for 30-0. A confident start.

But a double fault brings him back down to earth, and a miss on the forehand lets Djokovic in.

Cam Norrie returns to cheers. The umpire calls time.

Back down to business. It's a must-win fourth set for Norrie, who will serve first.

If Cameron Norrie is going to reach his first major final today, he's absolutely going to have to do it the hard way on Centre Court.

Novak Djokovic can smell an eighth Wimbledon final, with one more set required to book a meeting with Nick Kyrgios in Sunday's title decider.

Can Norrie deliver another twist and get the crowd believing again?

The Briton is heading off court before the fourth set. A chance to reset, before giving his all in an attempt to force the three-time defending champion to go the distance.

Centre Court is silenced, for now.

Cam Norrie hits the net with his forehand and Novak Djokovic takes a 2-1 lead.

Ace down the middle.

Two set points for Djokovic.

Norrie finds the net on the next point to bring up 15-15, then Djokovic puts in a drop-shot and is left with plenty of open court to get to 30-15.

A promising start for British fans as Djokovic whacks a backhand wide to go 0-15 down.

A break back would be huge here for Norrie, obviously.

Christian Evans: Norrie has got more chance of winning if he was playing against a brick wall, the ball would come back less!

Yes! Cam Norrie scurries forwards and hits a backhand down the line to get to 40-30.

Djokovic's return goes long next and Norrie holds again.

It would be easy to crumble when the six-time champion is two breaks up in a set, but Norrie is keeping himself in this.

It initially looks like all is not lost for Cam Norrie. He's got some solid serving of his own and Novak Djokovic swings his return wide to put the Brit 30-0 up.

But Norrie slaps a couple of forehands into the net and that's 30-30.

It's a very, very straightforward hold for Novak Djokovic.

Centre Court only responds with a few mutterings after solid serving from the Serb gets him 5-1 up in the third set.

Paul Christie: Hate to say it but Norrie looks completely out of his depth here

Lord Greystroke: Norrie winning the first set was analogous to a sprinter being 2 metres ahead of Bolt after 20 metres. I now fear the analogy will continue to the outcome at 100metres. Prove me wrong, Cam.

Dennis Ethan: Normalcy has been restored on the Centre Court

The atmosphere has gone a tad flat.

A stony(ish) silence at the end of that fifth game is pierced by the animalistic cry of celebration from Djokovic.

• Cameron Norrie made his ATP Tour debut in 2017 - Novak Djokovic has not lost at Wimbledon since then
• Djokovic would reach his 32nd major final with victory today - Norrie would reach his first
• Norrie was 12 when Djokovic won his first Grand Slam title in 2008

This is not good.

Cam Norrie hooks his backhand long and Novak Djokovic is now a double break up in the third set.

It's hard to see Norrie taking this set now.
