Carlos Alcaraz found his best form after a shaky start to beat Andrey Rublev and reach the Wimbledon quarter-finals as hot favourite in the women's draw Aryna Sabalenka also progressed.

The Spaniard, hunting a third straight title at the All England Club, has taken his fans on an emotional rollercoaster but is into the last eight after a 6-7 (5/7), 6-3, 6-4, 6-4 win.

While Alcaraz's main rivals, seven-time winner Novak Djokovic and world number one Jannik Sinner, are in ominous form, the second seed has blown hot and cold so far.

He will next face Cameron Norrie, who is the last British player standing at Wimbledon after beating Chile's Nicolas Jarry in five gruelling sets.

Alcaraz lost three sets across his first three matches and fell behind against Russian 14th seed Rublev under the Centre Court roof.

But he turned the match around in style, producing some of his best tennis in front of his adoring fans.

"I think I played intelligent and smart today against him, tactically," said the 22-year-old. "A really good match, which I'm really proud about."

The five-time Grand Slam champion said he always believes in himself, even when facing adversity.

"One point can change the match completely, turn everything around. In tennis, you have to stay there all the time," he added. "Being strong mentally, to stay there. I knew that I was going to play better."

Women's world number one Sabalenka has yet to drop a set in four rounds at the All England Club as every other top six seed has fallen, but was given a tough workout by Belgian world number 23 Mertens.

The Belarusian came through 6-4, 7-6 (7/4) against her former doubles partner to set up a clash against Germany's Laura Siegemund.

The three-time Grand Slam champion is making up for lost time after missing last year's Wimbledon due to a shoulder injury. She was excluded in 2022 as part of a blanket ban on Russian and Belarusian athletes.

"With your support guys I think everything is possible," said Sabalenka, who has never been beyond the semi-finals. "I don't know. It's such a beautiful tournament." (AFP)
