And Soares is soaring now! The Brazilian zings a return across court, into the tramlines and beyond the despairing Serena Williams. The top seeds get the break.

Two break points for the Brazilian-American pair.

Bruno Soares does superbly well to activate his go-go gadget arm and reach a high ball at full stretch.

Deep return from Nicole Melichar that tickles the toes of Serena Williams and she's unable to pick it up over the tape. Bruno Soares than floors Andy Murray with a vicious return. He'll be chased out of the All England Club if he carries on like that...

0-30.

A big shift in momentum on Court One.

Guido Pella holds to love to take a 3-0 lead in the third set.

Did Roberto Bautista Agut allow himself to get distracted by dreams of a first Wimbledon semi-final?

Goffin was terrific for three quarters of a set, Djokovic was even better throughout.

He's through to his ninth Wimbledon semi-final.

It's the Belgian's turn to wrong-foot his opponent.

30-30.

Djokovic then sets up match point by sprinting to the net and producing a sliced backhand winner.

Serena Williams winds up a forehand return, we saw a few of those missiles land yesterday, but drags it just wide. Soares and Melichar edge to a hold.

Error, error, error - and Guido Pella does fight back!

An uncharacteristic drop in performance by Roberto Bautista Agut sees Pella recover from 15-love down to win four successive points.

Interesting.

Goffin won't go down without a fight as he smacks down his fourth ace.

His forehand then barely gets to mid-height of the net.

Take that back.

Goffin then goes long. Really long.

15-30.

Saved! Bruno Soares leaps up from his spot by the net to meet two volleys with solid backhands. And it's deuce.

Guido Pella led 40-love in the opening game of the third set, but rather than a confidence-boosting hold to love the game quickly turns to deuce.

There's no sign of resignation in Pella's play yet, however, and for the first time in the match the Argentine holds in his opening service game of the set.

Fightback on?

Stunning return from Andy Murray on the backhand side, as Melichar and Soares seem to freeze.

And then the loudest roar of applause on court two so far!

Soares and Williams bat it between each other at close range but somehow Serena reacts to guide it away from the Brazilian. Great point. 30-40.

Murrena sense a break...

15-0.

Djokovic produces a Federer-like skip-to-the-net-dipping-forehand winner.

30-0.

The Serb eventually seals by wrong-footing the Belgian.

Goffin won his first two rounds easily. But he's not moving as well now in this third set. It's more mental than anything else. Lack of belief translates to heavier legs.

Murray thinks he's nailed an ace down the T. It's called long, he challenges... and Hawk-Eye falls in the favour of the line judge. Murray skips forward to slice a forehand volley into the tramlines on the next point for another hold.

Djokovic decides to challenge on a return that is called out. It was.

Goffin eventually holds.

The crowd cheer - in sympathy, largely.

How about that! Nicole Melichar runs off, arm in the air Alan Shearer style, celebrating a superbly weighted lob that drops beyond her American counterpart. Shot of the match...

30-30.

This looks to be a game where Djokovic is conserving energy knowing he's break up but he's decides to up his level after Goffin makes an error.

30-30.

Bruno Soares tickles a slice into the SW19 sky, but that's not a great idea when Serena is lurking... she grunts into a thumping overhead winner, before wandering off for a quick behind-the-hand whisper with Andy Murray. Williams goes after the next air-born return too. 30-0.
