In the end Kim Clijsters says her heart wasn't in the game anymore. The truth is her heart left the game after winning the 2005 US OPEN. The drive and the ambition was gone. Clijsters will probably be known as the best ever one slam wonder. Even Mauresmo and Mary Pierce have more slams then Kim and that's surprising. Clijsters says she had tough injuries join the club girlfriend everyone has had injuries but you don't see them complaining about it or whining to the media about it. I agree with Francesca Schiavone said about Clijsters at the Australian Open a few years back she just talks too much. So now that Kim's gone when you look at her career she was a chronic under achiever. Despite what Kim's fans say she will be known as a one slam wonder the kind of player that did not have the grit to be a great champion. Winning one slam means you only had one big moment that's it. A one slam wonder is not a great champion in my book. And Clijsters is just that. Now Justine Henin she is a great champion she has overcome lots of injuries and doubt and pain in her life. I admire Justine so much more she sees she has so much ability and talent and she wants to make the most of her tennis days. I feel Cljsters will regret this a few years down the road and by then it will be too late.
