I'm not saying I'm something special. I might play a little better tennis than other people, but it is because I was given the chance, and not many people are.

One day you can be a kid, but another day you have to be like this is your job, you play tennis. You have to work for that.

I was always at peace because of the way my mom treated me.

I went through very emotional things this year, like being in the French Open finals already feeling like you got it and kind of losing it.

I still speak Czech with my parents because I was born there.

The top players talk more now, and we have more meetings. We're just trying to get things better. But we still need somebody who could make a difference.

The game overall has gotten so much better, stronger, more physical parts to the game.
