I think luck falls on not just the brave but also the ones who believe they belong there.

We have a harder way to succeed in life as Serbs because of the past that we had and because of the history we had.

I haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.

Tennis players we're always playing in center courts that feel like arenas. And when we get on the court and the crowd cheers your name or salutes you - it's like you're a gladiator in the arena. And everyone is cheering - and you're fighting, you're screaming, during your strokes - it feels like you're an animal, fighting for your life.

I think if you do not enjoy your time, your life, if you do not live intensely and do not spend time with your family, in one way or another it will be reflected in your career.

I think luck falls on not just the brave but also the ones who believe they belong there.

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.
