This guy might not be able to get the smile off his face in the entire match. I had to go on Youtube to see a few highlights from him and his serve is pretty good.

This almost have the feel of a bit of an exhibition match. We have always loved an underdog in this country and there is probably no bigger underdog than Marcus right now.  

He was probably thinking he was going to quite the game and coach, and here he is playing Roger Federer on Centre Court.

So was once asked of another Willis. Marcus, on the greatest day of his sporting life, is staring around at Centre Court with an enormous smile on his face. Even Roger Federer is smiling, as if this were all some weird celestial wind-up.

Novak Djokovic has a good luck message for Marcus Willis.

"Everything is possible in sport," he says. "Roger is the heavy favourite but you never know. Willis is the home player, we will see what happens."  

Two men, both dressed in white, both wearing white bandannas. Except one has earned £74 million from tennis, and the other has pulled in £220 this year. 

Novak Djokovic, speaking to BBC One: "Fortunately I was scheduled on Centre Court, that helps on days like this and when the roof is closed the atmosphere gets even more special. It was fun.

"I do have a lot of expectations for myself but I am grateful that I am able to play at a high level so consistently. [Thirty grand slam wins in a row] is a stat I am proud of.

"I will continue playing with lots of passion and try to be dedicated and see how it goes."

Famous British Willis's until today: Bob, Wincey, Freeman Hardy. No longer.

Have a look at this shot by Djokovic, who managed to squeeze his return in to the bin at the side of the court. But I bet you already guessed what was going to happen from the very excellent headline.

Oh, you didn't...

Afternoon all, Fordyce here, everyone well? Can't decide what my Marcus Willis fact is - that, less than two years ago, he weighed 18 stone; that someone actually bothers counting past 700 when it comes to world rankings; or that he is a tennis coach at a boat club.

Novak Djokovic is 5-3 up in the tie-break when he comes rushing into his net, loses his footing and ends up on his bum. Are there banana skins on the grass? 

The Serb moves to match point but blasts a forehand long. Gaaaaah.

Another match point and Adrian Mannarino can only return into the net.

Djokovic is through. 

Adrian Mannarino is cool. Oh so cool. Even with the world number one peering over the net in front of him. 

After holding his serve, the Frenchman goes on to take the first point off Djokovic's with a lush drop shot. The crowd loved that one!

Then it's 0-30, after a Djokovic error. Blimey. 

But the three-time champion recovers and holds. We go to tie break.

Strolling round the grounds at Wimbledon, I bumped into a champion of yesteryear looking forward to Britain's Marcus Willis, who nearly retired earlier this year, taking on Roger Federer.

“Roger said a funny thing that he was trying to make a comeback too, because of his back injury. Their bank accounts probably aren’t quite the same," said Stan Smith, who beat Ilie Nastase to win the men's singles title in 1972.

“Willis is probably going out there with the view that he’s on Centre Court and doesn’t have to buy a ticket.

“I think it will be a relaxed atmosphere. He can play and he’s a left-hander. Federer doesn’t like lefties that much. ”

John Newnham: I'm putting my shoes back on, my feet are cold #Djokovic, external is taking too long   

Adrian Mannarino isn't ready to leave the grass just yet. He earns break point as he wrong-foots Novak Djokovic with a steady forehand.

The world number one takes it to deuce, but then hits long past the baseline. Advantage Mannarino. 

And the Serb can only conjure up a double fault. The Frenchman levels! Oh la la. 

Excellent work, you lot. 

Mike: Djokovic is just…damn. So good. Privilege to watch him.  

Novak Djokovic is ready to wrap things up on Centre.

He holds with ease, and the crowd ooh and ahh as he slices a backhand down the line to deceive Adrian Mannarino. Sublime. 

But the Frenchman isn't bowing out quietly. He holds his service game to love, seeing it out with a deft ace. Bosh. 

Djokovic to serve for the match.
