I am fast and very powerful on the court, so this is what matters.

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 have been through two wars in my 24 years, and I know what it's like to be without anything, to see the bombs flying above your head.

I never wanted to change countries; it's something that is part of me.

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'm a happy man, because I am successful in what I do, of course; but what makes me most happy is I have people around me that I love and who love me back. This, for me, is the most important thing. Nobody likes to be alone.

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