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.

Well, I do feel that I carry the responsibility of representing my country wherever I am, and this responsibility came with the success that I had in last couple of years, not just myself but the whole group of tennis players that comes from Serbia.

Obsession is a negative word, I do not think that obsession can bring positive things. Not only in tennis but, I mean in any situation of life.

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.

Nothing, nothing, nothing is better than sex, it is what God created us to do.
