In a press conference in Zhuhai Steffi Graf spoke about the differences between the men's side, where Roger Federer, Rafael Nadal and Novak Djokovic dominate, and the WTA Tour where Serena Williams rarely plays and the matches are very balanced.
Graf said: "Well it's obviously different periods in the evolution of the sport, in the different times. I mean, there's been times we had a lot of rivalries and then there's times when you don't. So I think the fun thing has been that it's been keeping it interesting, it's been -- a lot of players that play on the high level maybe sometimes struggle to keep it up all year long, but they're always capable.
And seeing especially the younger girls now just being less afraid and going out there and going for it. I just think it's become a lot closer, the level, and I think that's what makes it kind of interesting that you do not always know."
Graf also spoke about Kim Clijsters coming back to the competition: "Well I think that it will be fun to see. I don't know. But I think for her to make the decision that she wants to come back she must believe that -- I mean obviously I don't know what her goal is, but I think if you've been at the top the way she has been -- and she has come back once before, so she knows what it takes.
I would assume that she believes that she is capable of it and it will be fun for all of us to watch and see how she will be able to -- being a few years away from the sport, it's very difficult, and she's got family and kids, but we see it out there happening a few times now. So it will be a big challenge, but she seems like she's looking forward to it."
