The rain is expected to ease off in time for men's quarter-final action at Wimbledon on Wednesday but even if it does not defending champion Andy Murray and seven-times winner Roger Federer will have the Centre Court roof to keep them dry.

The roof showed its worth again on Tuesday with Johanna Konta's thrilling win over Simona Halep taking place during a downpour.

Konta is the first British woman through to a Wimbledon semi-final since 1977.

Murray is first up on Centre Court against American Sam Querrey followed by Federer's tough test against Canadian Milos Raonic.

The Number One court will also have a retractable roof in place by the 2019 tournament but for now Novak Djokovic, who faces Tomas Berdych, will have to hope the weather is kind to him.

Also on Number One, Luxembourg's Gilles Muller, who upset Rafa Nadal in a marathon five setter, is hoping to make seventh-seed Marin Cilic his next victim.

Djokovic explains his retirement

This is what Novak Djokovic had to say after his quarter-final retirement against Tomas Berdych due to injury:

"It's not the shoulder. It's the elbow that already keeps bothering me for over a year and a half actually. It's unfortunate that I had to finish Wimbledon this way. I mean, if someone feels bad about it, it's me. But, you know, I tried. I tried what I could do from yesterday, you know, to get it in the condition where I'm able to play. I was able maybe, you know, for 30 minutes to play with some pain that was bearable, let's call it that way. All the treatments and medications couldn't really help. The serve and forehand were the shots where I could feel it the most. Just after that there was really no sense.

"I spent probably about two hours, two and a half hours today on the table in between the warm-up and match, trying to do everything I possibly could to make me fit. But it wasn't to be. You know, for an athlete, especially in an individual sport, there is no way out. If you don't feel fit, unfortunately that's it. You know, there is no one to come instead of you."

Thanks for tuning in!

It's been another eventful day at the All England Club, perhaps the most eventful day of these Championships so far.

Andy Murray and Novak Djokovic, who have shared the men's singles title for the last four years, are both out and it is the majestic Roger Federer who is the last man standing of 'the Big Four'. 

Be sure to join us tomorrow as attention turns to British woman Jo Konta as she aims to reach the women's singles final.

Standing in her way will be the evergreen Venus Williams, five times a champion here and looking for her first major title since 2008. 

It's going to be a cracker!
