Mirra Andreeva is lucky that she has Conchita [Martinez] as her coach. She was a prodigy herself and Conchita is giving her all the secrets of how to deal with the media, how to deal with the stress, how to deal with a quarter-final match. It's really been helpful in her ascendancy up to the top.

One is a chatty 18-year-old long tipped as a future Grand Slam champion.

The other is a straight-talking 53-year-old former Wimbledon winner, who has also coached another top player to the title.

Together, Mirra Andreeva and her coach Conchita Martinez are forming a successful double act which they hope will lead to the Russian teenager also lifting the SW19 title.

It is a partnership built on playfulness, respect and lots of serious work.

Both women have spoken to BBC Sport to tell us what makes them tick.

It's been a strange sort of year for Iga Swiatek, who has been a fairly consistent presence at the top of the world rankings in the past three or four years.

She has reached numerous semi-finals and quarter-finals in 2025, but had not got to a final until the grass-court event at Bad Homburg prior to Wimbledon, in which she lost to Jessica Pegula.

That run took her back up to fourth in the world rankings, although she is seeded eighth at Wimbledon.

Mirra Andreeva and Belinda Bencic are both eyeing a first Wimbledon semi-final after enjoying career-best runs in SW19.

Andreeva, who reached round four in 2023, hasn't dropped a set en route to the last eight, most recently beating 10th seed Emma Navarro 6-2 6-3.

The seventh seed, who only turned 18 in April, would be the third youngest woman to lift the Wimbledon women's singles title in the Open Era.

Bencic, back at Wimbledon for the first time since becoming a mother in 2024, came through consecutive three-set matches in rounds two and three before eliminating 18th seed Ekaterina Alexandrova to reach the last eight for the first time.

The two players haven't previously met on the WTA tour.

Ah.

Queen Camilla definitely trumps my spot of Hugh Grant.

The Royal Box, and many in the crowd who have clocked her arrival, rise for the first actual British royal of the week - Queen Camilla.

She is sitting in the front row this afternoon to watch a couple of absolute crackers on Centre Court.

Over on Centre Court, Mirra Andreeva and Belinda Bencic have just walked out to a very warm reception.

Actor Hugh Grant is among those in the Royal Box.

A couple of unforced errors from Liudmila Samsonova put Iga Swiatek in control of the game and the Pole shows her radar is dialled in by crushing a backhand down the line for a winner.

It's been a good start for both players on the cusp of breaking new ground in their careers.

Iga Swiatek has never made the last four at Wimbledon and this is a first Grand Slam quarter-final for Liudmila Samsonova.

Liudmila Samsonova is getting plenty of first serves in early doors and although Iga Swiatek smacks one backhand away for a winner, the rest of the game is fairly straightforward for the Russian 19th seed.

Iga Swiatek starts her latest service game with a first double fault of the match.

She demonstrates her speed and nimbleness around the court and watches Liudmila Samsonova go long with a forehand to confirm another hold.

Liudmila Samsonova replies with a hold to 30 in bright sunshine on Court One.

Escape to victory!

Incredible effort from Julian Cash and Lloyd Glasspool to save those match points and then carry that momentum into the match tie-break.

The four players share warm embraces at the net, with Henry Patten graciously telling his opponents they did a "great job".

These two pairs know each other very well, of course. Cash made his name with Patten, while Glasspool was once Harri Heliovaara's partner.

Liudmila Samsonova makes a fast start and gets a break point in the first game of the match, but that's well saved by an ace by Iga Swiatek, who goes on to hold serve in the opener.

Lloyd Glasspool reacts quickly to meet a passing shot down the line and comes up with a winner for a mini-break.

Harri Heliovaara closes off the angle and hits a winner at the net.

Glasspool will have the chance to serve for the match.

After nearly burning my fingers on a sun-soaked court two for the men's doubles earlier, I've since hotfooted it to Court One for the start of today's singles quarter-finals.

The clouds have started arriving and that's cooled things down a touch as eighth seed Iga Swiatek takes on 19th seed Liudmila Samsonova.

Swiatek will serve first.

Harri Heliovaara and Henry Patten just won't go away.

They seal a second mini-break to get us back on serve in this tie-break.

Haari Heliovaara comes up good just when it's required to wipe off one of those mini-breaks with a winner down the line.

But Julian Cash gets the hold on his next serve.

Defending champions Haari Heliovaara and Henry Patten are on the brink of going out here.

Lloyd Glasspool seals a second mini-break with a volley.

Heliovaari goes on to hold.
