Serena Williams held a break point in that game but can't convert it. Juvan threw in a drop shot and Williams, charging forward, sent it well off target.

Juvan then holds her nerve to win the next couple of points to hang on in this set. Four-one and two breaks down and it would've been all done, instead we're at 3-2 with Williams, holding a break, to serve next.

This is the most focused I've seen Nick Kyrgios in a long time.

How long can it last?

Rafael Nadal's serve is impregnable. And Nick Kyrgios's returning is less impressive.

The Spaniard moves to 30-0 in a twinkle. And a drop-shot with the dexterity of a Michelin-starred pastry chef makes it 40-0.

Kyrgios twangs the wire with a backhand and is out of the game.

In a way though, it would only be buying insurance that he can't hold his serve for three straight games.

And Kygios does not like the sort of guy who spends a morning comparing different quotes.

Juvan thinks she has won the fifth game with a forehand down the line with Williams beaten, but it's just too long. The American then sends in an unstoppable return for deuce on the Juvan serve.

Tom B: It's hilarious, the ease with which Nadal very obviously and deliberately gets under Kyrgios' skin

Daniel King: Not sure Nick wants to push the 'slow play' thing too far. Whenever I've seen Rafa warned about it, he raises his game a notch.

Dave Payn: The problem is that Kyrgios wants to do it his way and put on his usual act and Nadal isn’t standing for it, so he’s getting his own back with the time-wasting. If Kyrgios can’t take what he dishes out he can walk off the court. He’s done that before.

A couple of staredowns from Nick Kyrgios which Roy Keane would have been proud of there.

The ringmaster is claiming the Centre Court circus.

A sublime drop shot saves one break points.

A reflex volley at the front of the court saves the second.

Two massive serves and the escape is complete. Nick Kyrgios is in the getaway car, over the border and into the changeover with a 3-0 lead.

We haven't fully seen that serve of Serena's yet. It's been one of the best in the game.

Serena Williams, as always, utilises her incredible power, blasting away a forehand that Juvan does well to get a racquet to, although she can't control the direction.

An ace, her first of the match, comes not too long after and Williams jumps to a 3-1 lead.

Rafael Nadal is the best player on tour at breaking back immediately after being broken.

A big backhand swat brings up 15-40 and two bites at the berry...

Craig: Kyrgios does have a valid point, only played one set and Nadal off for toilet break... 5 mins later after coming back Nadal thinks he's still entitled to sit down for more of a break... Umpire calls time and Nadal still sits there for a further minute or more.

Sarah Rimmer: Kyrgios might not be breaking any rules but at what point is anyone going to stand up to his temper tantrum playing?! He should be more grateful for his opportunity to play tennis at Wimbledon!

Ciaran L: How can Nadal have earned his right to play outside the rules? Boris, that's called cheating! If he's taking too long to serve then he should be pulled regardless if he's world no. 1 or 100.

That's how good he can play when he gets his emotions in check.

A good hold from Juvan, just stopping Williams running away with this set. But the Slovenian still has to find a way to break her opponent's serve.

Oh yes.

Nick Kyrgios absolutely laces a forehand winner down the line. Rafael Nadal was a spectator, might as well have had his feet up in the Royal Box.

Nick Kyrgios attacks the Rafael Nadal second serve, but his attempt to end the rally early ends in the net.

But a forehand that was so deep it needs treatment for the bends brings up 15-40 and two break points.

When Serena is on balance she has amazing power. Juvan is now looking up at her box quite a bit in the last couple of games, after taking that first set.

Serena Williams consolidates that break of serve. Now we will see what the 18-year-old Slovenian is made of.

Nick Kyrgios's slice backhand slides over the net by a whisker and suddenly he has 0-30 on the Rafael Nadal serve.

First serve missed by Nadal...

From a Kyrgios perspective I like the way he's managed to get some rhythm on his serve.

The ball toss sits the same but he can hit it in any direction. You can't read it and that's starting to give Nadal problems.
