TENNIS: Wimbledon 2015: Serena & Venus Williams set for Centre Court clash

Serena and Venus Williams play each other for the 26th time when they meet in the fourth round at Wimbledon on Monday (first match on Centre Court at 13:00 BST).

The Americans, who have both won five Wimbledon singles titles, share an incredible 27 Grand Slam titles.

Elder sister, Venus, 35, has steadily been recovering her form over the last 18 months after suffering from a debilitating autoimmune disease. 
 
However, there has been no stopping Serena and the 33-year-old claimed her 20th Grand Slam title at the French Open last month to edge closer to a second 'Serena Slam' and her bid to win all four majors in a calendar year.

Serena on Venus

"She's my sister today, she's my sister next week, she's my sister next year: I think that's a little more important than a match.

"It's unfortunate that it's so soon in the tournament, but we're going to do the best that we can. We'll leave everything out on the court. When it's done we'll go back to regular life.

"I expect more people to be rooting for Venus. I would be rooting for Venus. She's been through so much. She's been so inspiring to me and to a lot of people with the same things that she goes through. She's just an incredible individual.

"I just don't know how I'm going to do, to be honest. I'm playing the toughest player I've played in women's tennis."

Venus on Serena

"There's no easy points against Serena. No matter how Serena's playing, she knows how to win.

"I'll probably be cheering for her. No matter what she's been through, she's never complained.

"You see players that continue to talk about injuries that are like 9,000 years old.

"She never complained once. You have to give her credit for that. She's gone through so much that no one could even imagine."
