My father believed in me many times more than I believed in myself.

My father never talked about the sacrifices that the family made for me.

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.

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.
