Let's hear from Yulia Putintseva, who has defeated top seed Iga Swiatek to reach the fourth round:

That was an inspired performance – how did you beat the world number one and top seed?

"Feels great, I don’t know I was just so focused on just playing fast and not give her any time and that’s pretty much it."

What were your tactics?

"There was a tactic to play my game and as my coach sad stay intense every point and that was working.

"I was thinking during the (match) that I beat the world number one on grass (Naomi Osaka) so I think it was meant to be."

Where do you get your fiery personality?

"My childhood, I was always really fired up as a kid and honestly I have no words, you guys bring me back to life after the first set.

"This is crazy guys it was great energy from all of you and I was trying to entertain you more and more with my shots and I was taking energy from you guys."

Next up is another fiery player, Jelena Ostapenko:

"Can I just rest for the moment and not think about what I have to do right now?

"Come back to practice tomorrow and see what I can do against Jelena."

Off we go. Novak Djokovic to get us started on Centre Court. The seven-time Wimbledon champion does still have strapping on his knee of course. We'll see how that affects him today.

Australian Alexei Popyrin has only made it past the first round once before this year, in 2019, meaning this is his furthest run at the All England Club.

He has been handed the toughest of draws in second seed and seven-time Wimbledon champion Novak Djokovic.

Ranked 47th in the world, he will look to cause an upset on Centre Court.

The men's players are being worked hard for their money this year.

There have been 33 matches so far which have gone to deciding five sets - a new record through the opening three rounds at a Grand Slam.

An interesting stat from Opta.

Yulia Putintseva is the first women's player since Alison Riske beat Ashleigh Barty in 2019 to win against the world number one at Wimbledon after losing the first set.

Novak Djokovic suffered a bit of a scare in his last match against Britain's Jacob Fearnley, ranked 277 in the world and appearing at his first Grand Slam.

Fearnley was two points away from taking the match into a deciding set before 24-time Grand Slam champion Djokovic came through.

But it remains to be seen just how far Djokovic can push the knee that he had surgery on just weeks before arriving at the All England Club. An injury that saw him pull out of the French Open.

Who saw that coming when Swiatek won the first set without too much difficulty?

Putintseva is appearing at Wimbledon for the 10th time and had never previously gone beyond round two... she is now in the last 16 after beating the world number one.

The Kazakh faces Latvian 13th seed Jelena Ostapenko next.

Here come seven-time winner Novak Djokovic and Alexei Popyrin for the final match on Centre Court this evening.

A straight forward win for the third seed or a shock on the cards?

They are back under way on the outside courts now and the sun is shining.

Fifth seed Daniil Medvedev is currently in the fourth set against Germany's Jan-Lennard Struff on court two.

It's still on serve but Medvedev seems to be in a hurry. He won his first service game after the delay to love in little more than a minute and his next didn't take much longer.

Struff will serve to stay in the match.

The roof is off and it's turned out to be what looks like a lovely evening in SW19.

Out come 24-time Grand Slam champion Novak Djokovic and Australia's Alexei Popyrin to an already packed out Centre Court.

What a way to spend a Saturday evening, eh?

Swiatek saves the first as Putintseva scuffs a forehand wide.

The Pole uses all her experience to save the second too - running Putintseva up and down the baseline before she eventually hits into the net. Deuce.

Putintseva places a forehand right on the line and Swiatek is nowhere to be seen.

The Kazakh has two match points.

Putintseva takes the first point.

A telegraphed drop shot offers Swiatek an easy chance to level and she takes it. 15-15.

Yulia has done an exception job of changing her tactics and Iga has been unable to respond or find a way to stem the flow of momentum.

She’s given Iga no time to breathe.

Fine work from Putintseva to get back to second deuce but she can't build on it as a long forehand hands advantage to Swiatek.

And the Pole holds.

Putintseva will serve for the match.

Swiatek leads 40-30 but Putintseva gets to deuce thanks to a shank into the net.

Swiatek digs out her fifth ace of the match for advantage.

Swiatek pulls it back to 30-30 and delays Putintseva's celebrations a little longer.

It really is falling apart for Swiatek as she completely mis-hits a drop shot and Putintseva leads 15-0.

A double fault puts the Kazakh 30-0 up.

Incredible shank from Iga Swiatek at the net. That was one of mine.
