Sisters Venus and Serena Williams remain on course for a family Wimbledon final after all top four seeds reached the semi-finals of the women's singles, at Wimbledon. Defending champion Venus and two-time winner Serena were both in top form as they beat Agnieszka Radwanska and Victoria Azarenka respectively.Top seed Dinara Safina, who struggled through three sets against Sabine Lisicki, stands in the way of Venus in their semi-final. Serena will play Elena Dementieva, who beat Francesca Schiavone 6-2, 6-2.



Venus looks like the one to beat as she bids to win her third consecutive women's title - she has not dropped a Wimbledon set since the third round in 2007.



"I'd like to say I feel invincible, but I work really hard every day to achieve these victories," she said.



"I feel that Serena and I work real hard.If it was so easy, we'd win everything.But it's not that easy.



"We still are definitely the frontrunners in tennis as far as, you know, being some of the best players out there.But if there were just two players, it would just be a final.There's got to be 128.So that's the way it's got to be.I look forward to the challenge of whoever's across the net."



Serena discussed the Williams success by adding: "We have a great game.We have strong serves.I think we have pretty good returns.Just solid all around court players.I think we both move pretty well.So, I think that's a pretty solid game.



"And, honestly, I just feel lucky and blessed to have had such a good coach in my dad and my mom to have taught us this game."
