*Serena Williams will compete in her sixth Wimbledon singles final on Saturday in a match against Russian Vera Zvonareva, but the defending champ says she’d rather her opponent be someone a little closer to home – her sister and roommate, Venus.

“I would feel like I would almost rather play her because at least I know for certain one of us is going to win something and take something home. But now it’s a 50-50 chance,” Serena told reporters. “I didn’t realize how good a feeling that was.”

But Serena said she still had the same motivation to fight on Centre Court tomorrow’s for her fourth Wimbledon singles crown.

“No matter if Venus had won and I’d be playing her in the finals or not, I would still feel really into it and really like I want to do this,” Serena said.

Venus, a five-time Wimbledon singles champion was knocked out in the quarter-finals by unseeded Bulgarian Tsvetana Pironkova, in a stunning upset. Also, both sisters – who have won 12 Grand Slam doubles titles, including four at the All England Club – were knocked out of the ladies’ doubles at the quarter-finals.

As for her chances against 21st seed Zvonareva, who will be playing in her first Grand Slam final, Serena isn’t taking anything – including her wealth of experience – for granted.

“On paper it looks like I should win. But Vera, I’ve played her several times; she’s beaten some good people,” Serena said. “Her last two matches she’s been down a set, so she’s obviously a fighter. She never gives up.

“I’ve been in this situation before where I did put pressure on myself and actually ended up losing. I learned from that hopefully. I just don’t want to put too much pressure on myself.”

Zvonareva, meanwhile, has beaten Serena in the past and, with that memory for inspiration, she makes a passionate case for why she can upset the odds again.

“I remember I played a very good match against her in Cincinnati one year, and I was able to beat her,” she said. “There will be moments where she doesn’t make a first serve. I haven’t seen anyone make a hundred percent of first serves. So then you just have to take your chances.”
