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.

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. And athletes in general are, in this moment, the biggest ambassadors that our country has.

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.

People look up to me as somebody who is able to switch the image of our country from negative to positive.

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

I love football and it's the sport I would really like to play. I've said on national television here that I would really love to play for one of our football clubs when I finished my tennis career.

I cannot guarantee anything.
