I am grateful to life. And also to the people who have brought me here. Without them, I could not be where I am now.

My father had never watched tennis, never liked tennis too much. He said, 'OK, we buy a racket, we watch together,' because we didn't know anything. It was a process of learning together that made it more interesting.

My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.

Coaches are very important to players. They're people that are mentors, people that are advising them, people that should be their friends and somebody you can rely on on the tour.

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.

I understand that the results I've had in my career, or I'm having now, they are very good. And that gives me confidence, of course, but I do not feel invincible.

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