Many say that (Pete) Sampras is the greatest player. But I say with all due respect to the rest, that he (Roger Federer) is the most complete player in the world so far.

If you get operated, something can go wrong and you can just say bye-bye to tennis. That's what happened to a lot of soccer players in Europe. They get operated, some things, it's not the mistake of the doctor. It's just some surgeries, they just don't go the right way...My injury will never go away. It's already become so chronic there's no chance to fix it so I can play without pain.

One of the most important things, actually, when you're playing on grass, is to move.

No matter what happens, tennis is still tennis: You can see a lot of great matches, a lot of new people.

You know why I want to win? Because of 15,000 reasons inside of the tennis court.

You cannot change me; this is the way I am.

I achieved what I want to achieve and I want to continue doing something else.
