What others said about her retirrement

We should never forget what Kim Clijsters has done for tennis . . . we have lots of respect for each other, but we were rivals. I think it's been a good concurrence for us and she's been a great player and it's time for now to turn the page and do something else in her life and everyone has to respect that.

Justine Henin

I feel her best tennis was yet to be played. Unfortunately we will not see it, as Kim fell in love and tennis is the loser here. Kim is a class act on and off the court and tennis will miss her.

Martina Navratilova

I hope she'll have a great time in her life after tennis. I always said that when the Williamses were at their best, she was the only one then physically, who could maybe beat them. I also think you should never count her out; look at me, I came back, and she's still very young. She could have more tennis left in her.

Martina Hingis

I wish Kim the best in her life after tennis. She was a great player, a great competitor and an even better person. We had some great matches but I'll miss her more in the locker room than anything else.

Serena Williams

I think she had been thinking about retiring for a while so I'm sure she is really convinced that it's the right decision for her. The Sony Ericsson WTA Tour and all the players are going to miss her a lot, not only because of the player she was, but the joy she brought everywhere. I wish her the very best in her new life.

Amelie Mauresmo

It was a surprise for most of the players because she (Clijsters) had said she will see out this season, but it was not to be. Maybe she doesn't have the motivation to keep on playing and is looking forward to the next phase in her life.

Nadia Petrova

I think it is a private decision and we have to respect that. I just want to wish her well in the future.

Dinara Safina

Kim's so well-liked around the world and she's played well in so many tournaments around the world that it would have been nice for her to compete for the rest of the year. But I know how many injuries she's had over her whole career, she's had to play through some tough times."
