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'm very fortunate to have the support of the people around me, I feel happy because my wife helps me and people who are close.

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

We spent all day travelling, living away from the people you love, not sleep in our own bed ... We are far from our own houses. We live in hotels, clubs. And now that I am a father it is much more difficult.

Building a solid foundation in the early years of a child's life will not only help him or her reach their full potential but will also result in better societies as a whole.

I am fast and very powerful on the court, so this is what matters.

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.
