Is always the motivation to play better and better. But I think we are in a very good way to keep winning matches. That's most important thing for me.

The bad thing about the [tennis] calendar is how it is made and obligates you to play tournaments all year. If you want to achieve the most you can (and) go as high up (in the rankings) as you can, you have to play from the start to the finish because there are important tournaments from the beginning to the end.

I don't think about how going to be the match. I think about try to do the right things to win. I don't think about how easy can say or how tough can say. I go on court. I try my best.

A lot of times I had some problems, but I always had the passion and the personal motivation to keep going, to keep working hard, keep fighting for the things that really motivates me. That's all.

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.

As a tennis player you can win and you can lose, and you have to be ready for both. I practised self-control as a kid. But as you get older they both - winning and losing - get easier.
