Basically I started playing double handed on both my forehand and backhand side because my first racket was very heavy.

Roger Federer is stylish.

My greatest point is my persistence. I never give up in a match.

As tennis players, we work and we sacrifice many things. To lose, that's not a happy thing - I mean sure, I was disappointed. You have to come back strong. But to win the last point in a grand slam tournament, that's the most beautiful and most satisfying feeling you can get as a tennis player. It's worth it.

Tennis is a traditional game. A big sport like tennis does not need too many changes. The game has become too fast, there are hardly any long, interesting rallies these days. So maybe slowing down the courts could help. But you can't really stop a sport from evolving.
