It was very unusual for a boy to play tennis in my country.

In my case, I can sincerely say that nothing is impossible... When I was saying I want to be No. 1 of the world, and I was seven or eight years old, most of the people were laughing at me because it seems like I have one percent of chances to do that, and I've done it.

When the last point is done, we are humans. Give your opponent a hug and say, ‘great fight,’ and that’s all.

... the winner is the one who believes in victory more.

I had a nice childhood. War and all the experiences affected me as a person and helped me to grow, to change.

In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.

The confidence is there, the game is there, but physically you can't fight nature sometimes. You can't do much about it.
