I like my groundstrokes, I can say. I like it. That's my game - I'm a groundstroke player and I play pretty aggressive.

I always try to show my human side to my colleagues and to the whole circuit. More than anything because we are all on the same train, it is part of our work.

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.

Even though now I'm pretty popular in my country and tennis is the No. 1 sport, and I'm very flattered that the people recognise me and come up and give me compliments, I'm more a person who likes to have privacy and peace.

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.

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 trying to enjoy my lie as much as I can and I know that tennis hopefully is going to be my life the next 10, 15 years.
