The minute you think you know everything about tennis is the minute your game starts going down the tubes.

People say I'm around because I have a lot of heart, but I know all the heart in the world couldn't have helped me if I wasn't physically fit.

I think my greatest victory was every time I walked out there, I gave it everything I had. I left everything out there. That's what I'm most proud of. I can't go win Wimbledon anymore, so if what I've done in the past is not good enough, let it go. Because I'm certainly not sitting around thinking about it.

[In the modern game] you're either a clay court specialist, a grass court specialist or a hard court specialist... or you're Roger Federer...

People don't seem to understand that it's a damn war out there.

I was never part of the crowd.
