I always tried to win. I was as competitive as I am today.

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

Joking around is part of my personality, just who I am.

I am fast and very powerful on the court, so this is what matters.

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.

My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.

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