Certainly I would like to have some of the qualities of other players and obviously from Roger Federer. But believe me, there are plenty of other abilities that are important, particularly mindset and strength.

I am not the most courageous guy in the world outside of the court.

Everybody is doing the best things possible to still healthy and to play as long as possible.

You just try to play tough and focus point for point. Sounds so boring, but it's the right thing to do out there.

I have no sense of humor about losing

I am happy with being a tennis player and the choice I took when I was 12. But clearly, if I wouldnt have been a tennis player, I would have loved to be a soccer player. But again, I am happy with the choice I made.

What distinguishes tennis is respect for one's opponent, one's conduct on the court.
