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.

I always had the theory that the most important thing is be happy, enjoy what are you doing, and be fresh mentally.

Even if I have already peaked, I have to believe I can improve. I wake up every morning, and go to practice, with the illusion that I'm going to get better that day.

The US player Andy Roddick reaches speeds of 220 kilometers per hour when he serves. If I train with him every day, I will later be at an advantage against a player whose service crosses the net at 190 kilometers per hour.

I always wanted to be honest with myself and to those who have had faith in me.

Seriously, I am not a person that I think much about what happened or what didn't happen or what could happen. I happy about the things that happened to me. I'm a lucky person, for sure, for all the things that happened to me during my life.
