It is always in my mind still that I can crush anybody. That's not an issue. But I think that is the same for most athletes. If you don't believe you can win tournaments anymore, then you can't do it.

The week before the (US Open) I gave a few interviews for CNN, USA Network, New York Times, USA Today and Sports Illustrated which had been arranged beforehand. The reason for giving these interviews is not only because working with the media is just part of the job, it is much more my desire to contribute to the promotion of tennis in the U.S.

I have two lives, and all the problems I might have, I feel like I drop them once I step on to the match court.

It's not so simple to just stay in the moment and trust your game and your strength that you can turn it around.

You can be stubborn and successful or you can give it up a bit and change things around. For me it's important to have a bit of both.

I'm at the top of my game so, when I win or lose, I don't freak out...I don't think we can call it a rivalry yet. There's just to many great players around.

I've done so many interviews over the years in so many different languages. Radios. Papers. Magazines. There's always another interview to do. It's quite something, I have to say.
