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.

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 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.

Each year represents new challenges and obstacles. You have to adjust.

Obsession is a negative word, I do not think that obsession can bring positive things. Not only in tennis but, I mean in any situation of life.

I am the greatest tennis player. The other players are like coins in my pocket that I give to a homeless man.

I lost to a better player who played some courageous tennis and deserved to win.
