I lost to a better player who played some courageous tennis and deserved to win.

In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.

This time last year I would have said Federer would beat Sampras's record. Now I'm not so sure. His aura has gone. He's not as dominant as he was, and since I beat him in Australia he's looked frustrated. Players are beginning to challenge him now, especially myself and Rafa. He's got 12 Grand Slams to his name and maybe he will beat Sampras, but now I'm here it will be tough for him.

Pressure is part of what we do. It's always present.

I don't think, that you can always - you can ever - get your game to perfection, you know. Only if you're Federer.

I don't like to compare years, honestly. I think every year is a different experience, a different challenge. You grow. You evolve as a person and as a player.

It was very unusual for a boy to play tennis in my country.
