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

Last four months were great for me, was probably one of the best four months of my career, playing unbelievable in the clay court season.

I'm only superstitious on the tennis court.

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

I tried to find a solution to the problem that I had, tried to find a way to start playing better.

Some people may learn something from the way I play tennis. But there are also players who are better than me in certain techniques.

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.
