There's plenty watching on the Hill...

A slap of a forehand gets Novak Djokovic in front, before Kyle Edmund surprises the Serb with a rush to the net and a backhand volley winner.

There's a puff of chalk dust as Djokovic cranks down another ace for 40-15, and he holds when Edmund strays just long with a forehand.

Amanda: Footie sorted... now need Kyle to win!

Holly: Well done England!! Now come on Kyle Edmund.

Meg: It's coming home round 2 pls?

There's a huge swell of noise whenever Kyle Edmund finds a winner or outpaces Novak Djokovic with his serve.

A huge second serve is lashed long by Djokovic, and Edmund darts forward and nails the ball into the corner of the court to hold to 15.

Kyle Edmund earned his first win over Novak Djokovic at the fourth attempt earlier this year at the Madrid Open.

But that was on clay. And only over three sets. Does that victory matter today?

"Of course it does," his coach Fredrik Rosengren told BBC Sport yesterday. "Every match when you beat the bigger names, you grow in confidence and know that you deserve to play these guys.

"Whatever happens it will be a good thing for his improvement to play this match.

"It will help him the next time he steps onto the centre court anywhere in the world, it’s about playing big names on big courts."

Novak Djokovic clatters down an ace first up and gets himself to a 30-0 lead, before he flaps a forehand into the net.

No bother for Djokovic, though. An Edmund forehand strays long and the Serb wallops a big serve out wide to hold.

What a shot!

Edmund reaches out at full stretch to wrap strings around a Djokovic passer and coax it back beyond the Serb down the line.

An important hold.

The British number one steadies himself, adjusts his baseball cap and then engages in the longest rally of the match so far with Novak Djokovic.

It's Kyle Edmund who wins the baseline battle - one break point saved. Djokovic skids across the Centre Court turf to reach a wide forehand, but Edmund punches a volleyed winner down.

Two break points saved. Deuce.

Edmund dances around a short return and sizzles it down from shoulder height, Djokovic zips across to get strings to it but can't help it on target and the Centre Court crowd love that.

Gasps follow, though... Edmund wraps a groundstroke into the tape and all of a sudden Djokovic has two break points.

The early stages are important for Kyle to try and establish himself. And also put a bit of pressure on Djokovic and see if he is still mentally strong.

Explosive start from Novak Djokovic, the former world number one sprinting to 40-0 before Kyle Edmund gets bat to ball to get off the mark.

The Serb takes an opening hold, though, wrong-footing Edmund with a neat backhand.

Right then, it's the British number one against the three-time Wimbledon champion...

Novak Djokovic will serve first.

Kyle Edmund's coach, Freddie Rosengren, on the match against Novak Djokovic: "I think the thing is to make him grow as a person a lot. To enjoy this. This business is so serious anyway and if as a 23-year-old you’re not enjoying it, it's worth nothing.

"Kyle has a lot of respect for him [Novak] but this is what he’s working for. He can go in on the biggest, most famous court in the world, playing one of the best guys ever.

"You have to find a balance. He has to go in there trying to have a good balance and try to win. From now on he has to see himself leaving the court very proud."

Kyle Edmund strolls out on to Centre Court to a rapturous reception from the pleased-as-punch home crowd. The transition between the football and the tennis could not have been smoother.

Two guys in front of me are wafting mini St George's Cross flags as national pride hits Wimbledon.

The only slight disappointment is Kyle doesn't come out from the locker room in his Three Lions shirt...

Former British men's number one John Lloyd says Kyle Edmund possesses the right elements to overcome his more illustrious opponent.

"He has tremendous strike ability from his first serve and forehand - his forehand is in the top five in the world," said the 63-year-old.

"Since reaching the 2018 Australian Open semi-final his backhand - which was his weak link - is very good now. His movement is also better, although he doesn't have the flexibility like Djokovic or Andy Murray.

"He's not a one-pace player and has the weapons to beat Djokovic."

Prior to this year's tournament, world number five Marin Cilic told The Tennis Podcast , externalthat Novak Djokovic was not reading the ball as he once was and was not punishing his opponent's weak serves.

"Just looking from the other side of the net, I feel that in some shots he was maybe executing them a little bit better [before the injury]," Cilic said after beating the Serb in the final at Queen's in June.

"Even today, I didn't have such a good percentage executing the first serve and he was giving me some chance to stay with him. I had a lot of second serves and some of them he was missing."

Can Kyle Edmund exploit those potential weaknesses?

Edmund has won a lot of matches, he's done a lot of winning, he's been in the semi-finals of the Australian Open so he's getting used to being at these occasions. He looks like he is moving better on this surface,I think he's feeling the most comfortable he has ever done on grass, it's been not his natural surface.

Understandably Kyle Edmund's coach Fredrik Rosengren wouldn't divulge how his charge could hurt Novak Djokovic today.

"Everybody knows he has to play well," the Swede told BBC Sport yesterday.

"But he is as calm as he appears. He is in unbelievably good shape mentally, we talk a lot about that – to enjoy it.

"It is more about the belief, the belief he can do it. He showed that before and find the balance between not being too excited but still play to win the match."
