There is no such thing as a perfect player; it doesn't exist.

Don't get too excited when I am winning, and don't get too depressed when I am losing. Just keep it cool.

Probably I'll not be so successful if I will keep everything in myself inside of me.

There wasn't a rich father or rich family that paid for everything that I have right now, so I worked my way.

I pass through the difficult moments in life, really difficult times on grass, during my seven years of my career. All of a sudden I felt comfortable.

I think it's difficult to be No. 1. 'There's too much attention, too much expectation from other people.

I was very competitive. I hated losing. No matter what, I had to win.
