I haven't been in tennis for that long, but what I can say is that we have a lot of young guys at the top who are willing to do a lot of good things for tennis in general.

Obsession is a negative word, I do not think that obsession can bring positive things. Not only in tennis but, I mean in any situation of life.

In terms of playing ability there is nothing to choose between number one and 100. Instead, it's a question of who believes and who wants it more? Which player is mentally stronger? Which player is going to fight the hardest in the big points? These are the things that determine who is the champion.

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 embraced, I think, the process of becoming No. 1 of the world, which was long and difficult, but it's sweeter in the end.

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

I think if you do not enjoy your time, your life, if you do not live intensely and do not spend time with your family, in one way or another it will be reflected in your career.
