In my case, I can sincerely say nothing is impossible.

Nadal's the best player in history on [clay], and he is one of the best-ever players that played this game.

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.

Pressure is part of what we do. It's always present.

My success has a lot to do with my private life. I've matured a lot by first becoming a husband and now a father. My life is in the right direction. And that helps a player to thrive. One thing is linked with the other. My private life has helped me.

I embraced, I think, the process of becoming No. 1 of the world, which was long and difficult, but it's sweeter in the end.

I've had my ups and downs in my private life.
