It's always interesting watching the players walk out on court for these massive matches. A first Wimbledon semi-final for both Coco Gauff and Karolina Muchova.

Gauff strides to her with her chair with her headphones on, head down, looking locked in.

Karolina Muchova looks a lot more relaxed as she slowly strolls to her seat, soaking up the atmosphere.

Coco Gauff won at Roland Garros last year, she is still only 22 but she calls herself a veteran!

She has really developed her all-court game. She covers the net extremely well. She has played a lot of doubles with Jess Pegula who she beat here in the singles.

I think her backhand is the best in the game, it is lethal.

She has so many different choices and ways to win points.

Whatever happens, we will have a first-time winner in the women's singles this year.

Both Karolina Muchova and Coco Gauff will be thinking, why not them?

The players have emerged on to Centre Court to warm applause.

It's not as warm as the weather though, it is an absolute scorcher in south London today. These are elite athletes, but the conditions could still be tough.

Karolina Muchova is dominating the rest of the field, the way she is capable of moving forward and being so efficient when she does.

She has an incredible ability to play the angles and behind that first serve she is barely losing a point.

The way Muchova has been able to move forward will be the key today. The problem she is facing against Coco [Gauff] is her athleticism and how she can play the passing shots.

That match-up is fascinating today.

She has played incredible tennis. She is quite crafty, Muchova.

You feel over the years that injuries have really hampered her, because whenever she does play she just seems to win, but her body has constantly been letting her down.

I'll be interested with her really aggressive forehand on the crosscourt, is she going to be looking to attack the backhand of Gauff. Her sliced backhand, she has a really nice hand-skills set, so she will be looking to expose the grip on the forehand of Gauff.

It's an interesting match-up, and the Czech women on the grass have a history of performing pretty well on Centre Court.

Coco Gauff admitted she had surprised herself by reaching today's Wimbledon semi-final given her previous struggles on grass courts.

Two-time Grand Slam singles champion Gauff had never previously gone beyond the fourth round at the All England Club and suffered a first-round exit last year.

But a battling victory over Jessica Pegula set up a last-four tie with Karolina Muchova today.

Gauff's past four matches have all gone to three sets but the seventh seed's fighting spirit and supreme athleticism has seen her through.

"It feels really special considering the results I've had of late, especially on this surface," Gauff said. "I think I'm able to relax a bit because I just feel, regardless of how the rest of this tournament goes, I've found a breakthrough on grass.

"I'm just proud of myself. Obviously I'm not satisfied - I want to go all the way."

Coco Gauff, what she does better than anyone else is dealing with what she has on the day.

Coco's mental strength, her ability to work with what she has on the day, to accept the shortcomings with her game and just get on with it. You can never write her out.

I'm not sure anyone, even herself, would have put her in the semi-finals this year going off her first one or two performances. Especially with her extreme grip on her forehand, the yips on her first serve, she has had a biomechanics person come in. They're two shots you would think would be so important on the grass, but she just gets on with it and here she is in the semis.

The first match out on Centre Court today features a Grand Slam winner looking to conquer Wimbledon and an experienced Czech looking to get to a Wimbledon final for the first time.

Seventh seed Coco Gauff takes on Karolina Muchova today for a spot in the final on Saturday. Neither have been at this stage at SW19 before.

The pair have met seven times during their careers and two-time Grand Slam singles champion Gauff has won six of them.

However, their last meeting was in Stuttgart this year and it was Czech Muchova who came out on top 6-3, 5-7, 6-3.

Gauff is looking to add Wimbledon to her US Open and French Open titles while Muchova is in her fifth Grand Slam semi-final looking to reach her second major final after the 2023 French Open.

Who will come out on top?

There's more hope of British success in the men's doubles as Great Britain's Henry Patten and Finnish team-mate Harri Heliovaara are second out on Court One in their semi-final later.

Top seeds Patten and Heliovaara, champions at the All England Club in 2024, face American Aleksandar Kovacevic and Australia's Thanasi Kokkinakis.

They only joined forces in 2024 but captured the world number one ranking for the first time in June.

The duo won their second major title at the 2025 Australian Open and will now seek to reach a fourth Slam final.

They reached the last four by battling back from a set down for the second straight match to defeat Argentine Guido Andreozzi and Frenchman Manuel Guinard 2-6 6-4 7-6 (10-6) in the quarters.

They follow the first semi-final between El Salvador's Marcelo Arevalo and Croatia's Mate Pavic and German pair Kevin Krawietz and Tim Puetz, which is about to get under way on Court One.

You can watch that match uninterrupted via the "Watch and listen" tab at the top of this page or on the BBC iPlayer.

How's this for an omen?

Goran Ivanisevic was the last wildcard to reach the semi-finals of the Wimbledon men's singles - he went on to win the title in 2001.

He has been speaking about what fellow wildcard Arthur Fery needs to go all the way too.

"He is in the biggest semi-final in tennis," Ivanisevic told BBC 5 Live.

"He just has to keep enjoying it. Once you stop enjoying, that is not good. He is in the perfect position with the whole country behind him.

"He is a great player with a bright future. So enjoy it, take the crowd and just play good tennis."

Arthur Fery will need to take Alexander Zverev out of his norm. He is comfortable on the baseline and he likes to take his time ripping into rallies, so you have to bring him forwards sometimes.

It isn't a bad idea to bring him into the net because he is good for one volley but not often two.

So he will have to have his tactics in place and execute them, which he has already done well in this tournament. The other thing with Zverev on this surface is that he can pass great off both wings but he is deep in the court, so that gives the opportunity for the great mover in Fery to sneak in.

If he comes off the level he played at today, Zverev will give him a tough time though.

Arthur Fery will have the unknown factor against Alexander Zverev.

He needs to use that to his advantage because they have obviously never played. I'm sure Zverev will have seen him play a bit this week, but it is different to actually being on the court and facing him.

He won't know how the ball comes off the racquet or the different problems that he possesses.

We will shortly turn our attentions to the semi-finals of the women's singles, which will get under way from 13:30 BST with Karolina Muchova v Coco Gauff.

But first, let's get some more reaction to Arthur Fery's extraordinary run to the men's semi-finals.

Alfie Hewett, speaking after his straight-set win in the men's wheelchair singles quarter-finals: "He has a lot of weapons in all sides, strong forehand, backhand and serve comes through quick. Very good on the grass, if you get a bit of momentum, confidence, it can be difficult to break that.

"I rode my luck a little at 5-4, but in second I just served a bit better and tried to keep the ball out of the spot a bit more."

On form coming in: "Every week is different. The slam weeks are always special and anything can happen. As much as I take confidence and performance from those results, it is is never a given so just happy to get through today's match."

On expanded grass court season and how much of a difference it makes: "It is incredible. We have been saying it for years that the more grass court tennis we can have the better for everyone involved.

"It is a real special time or us Brits. I don't want it to end so hopefully it can continue."

Britain's Andrew Penney has been knocked out of the men's wheelchair singles, losing his quarter-final 6-0 6-1 to third seed Martin de la Puente.

The Spaniard will next face defending champion and top seed Tokito Oda, who has just closed out a 6-2 6-2 victory against fellow Japanese player Takuya Miki.

Oda had previously defeated Britain's Gordon Reid in the last 16.

Alfie Hewett meanwhile will play Gustavo Fernandez of Argentina, the fourth seed at this year's Wimbledon.

Fernandez beat American Casey Ratzlaff 6-0 6-1 in his quarter-final.
