I have no sense of humor about losing
I tried to find a solution to the problem that I had, tried to find a way to start playing better.
What distinguishes tennis is respect for one's opponent, one's conduct on the court.
I'm only superstitious on the tennis court.
I think I am a complete player. I can play well on all the surfaces. For me, the clay might be easiest, but I am not a specialist on clay.
It's not the time to look for excuses.
