We spent all day travelling, living away from the people you love, not sleep in our own bed ... We are far from our own houses. We live in hotels, clubs. And now that I am a father it is much more difficult.

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.

I don't think, that you can always - you can ever - get your game to perfection, you know. Only if you're Federer.

Even though now I'm pretty popular in my country and tennis is the No. 1 sport, and I'm very flattered that the people recognise me and come up and give me compliments, I'm more a person who likes to have privacy and peace.

I never wanted to change countries; it's something that is part of me.

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.

I want to win and I feel that pressure, but my career will not be a disaster if I do not win there. It is a dream to fulfill.
