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

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

My strokes just weren't there.

I know that success does not come at once, it is not a thing achieved overnight. It is the result of many, many, many years of working and trying to achieve goals.

Coaches are very important to players. They're people that are mentors, people that are advising them, people that should be their friends and somebody you can rely on on the tour.

I physically feel very fit. I’m very motivated to keep on playing on a very high level. I’m going to try to use these years in front of me to fight for the number one of the world and fight for the biggest titles.

Nobody actually played tennis in my family.
