Clijsters, Federer discuss Nadal's defeat

Kim Clijsters and Roger Federer discussed Lukas Rosol's stunning five-set, second-round upset of two-time Wimbledon champion Rafael Nadal. Both watched the match.

"I just wanted Nadal to win and come back," four-time Grand Slam champion Clijsters said. "I think he did everything right to try to stay in the match, especially in the fifth set. But the guy played incredible. I'm curious to see how he's going to play [against Philipp Kohlschreiber] because a lot of times he looked a little bit arrogant out there. So I wonder how he'll react in his next match, if he can stay grounded, keep his feet on the ground, and try to keep that result going. Nobody cares too much. You can beat Nadal, but if you lose the next round ... I'm going a definitely watch him tomorrow and see how he will play."

Federer said that while his opinion is nothing against Nadal on a personal level, it was good to see that upsets are still possible.

"I think 15 years ago you had matches like this so much more often on the faster surfaces, that a guy could catch fire and just run through you," Federer said. "Today it's virtually impossible because you make so many more returns these days and conditions are so much slower with the elements. Whereas it was just amazing to see that it was possible. Okay, he didn't play like that for five sets, but in the fifth it was just a joke.  I was laughing because of his performance for 10 minutes after that. I couldn't believe that he pulled it off the way he did. Of course I do feel bad for Rafa because it's a tough loss; it's Wimbledon; it's the way things happen."
