I always try to adjust to the situation.

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

Imagine a part of the U.S.A., from which the U.S.A. started - where is the cradle of your history? This is Kosovo for Serbia.

I have been through two wars in my 24 years, and I know what it's like to be without anything, to see the bombs flying above your head.

I don't think there has been enough communication between the players and the tournaments. In one sense it's just as much the players' fault. Players talk between each other and in the locker room about things that can be improved and then when the time comes to talk and really do something about it they stop.

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.

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.
