When I go out to play, I still believe I'm as good as anyone out there. I don't have to prove anyone wrong. I know what I've done and how well I can play.

Tennis players go into a press conference, and almost every one of them is the same. We do very little differently on a day-to-day basis.

I'd much rather win in three or four sets than go the distance all the time. I seem to put everyone through the wringer quite a bit.

I've probably put up with more criticism than a lot of people out there. At the end of the day, you block out everything, especially with your personal life.

Maybe I have to work a bit harder on clay. It's a challenge and I've always liked challenges. Whether I will ever win the French and master playing on clay, who knows? But I'll give it a shot.

Everyone has to call 'time' at some stage.

I'm more in that Rafa Nadal high-energy high-octane mold out there. I wear that emotion on the court. That's how I play my best tennis. People either like that or not. And I can't change that: that's who I am on a tennis court.
