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

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.

I remember as a kid, I was improvising and making little trophies out of different materials and going in front of the mirror, lifting the trophies and saying 'Nole was the champion!'

Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.

I had a nice childhood. War and all the experiences affected me as a person and helped me to grow, to change.

It gives me goose bumps and little butterflies in the stomach when I start thinking about the 'golden slam.'

My nutritionist has done a great job in changing my diet after we established I am allergic to things like gluten - I can't eat pizza, pasta and bread. I have lost some weight, but my movement is sharper and I feel great.
