It's interesting that I had such a close relationship with my grandfather. Because your parents always judge you: they say, 'You shouldn't do this, you shouldn't do that.' But with your grandparents you have a feeling that you can say anything or you can do anything, and they will support you. That's why you have this kind of connection.

I always try to have something that keeps my mind relaxed, keeps my mind a little bit off tennis.

I had to listen to the classical music because it calms me down, calms my nerves down.

Not everybody can like what I do, and if you feel that somebody is coming up closer to you and starting the rivalry and everything, you maybe change your position to him.

I'm happy, my family's happy, everything is going well.

It gives me goose bumps and little butterflies in the stomach when I start thinking about the 'golden slam.'

My father never talked about the sacrifices that the family made for me.
