First of all, in any sport where you can measure distance, height speed and all of that, you see how athletes have changed their sport and made it better. I believe, with every generation, the sport has improved. Certainly, in the men's game, that has been the case. I think that I played Pete [Sampras] at his best, I played Roger [Federer] at his best.. I believe wholeheartedly that Roger and [Rafael] Nadal have pushed the game much further than myself or Pete ever did. Their options on the tennis court are considerably more than ours.

Hate brings me to my knees, love gets me on my feet.

My feelings are Yevgeny Kafelnikov should take his prize money when he is done here and go and buy some perspective.

Hitting a ball dead perfect - the only peace.

I play tennis for a living even though I hate tennis, hate it with a dark and secret passion and always have.

If Pete’s (Sampras) child is a girl, my son will like her; if he’s a boy, my son will defeat him.

Success doesn't always come in the form of a trophy. Keep striving for success.
