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

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.

It gives me goose bumps and little butterflies in the stomach when I start thinking about the 'golden slam.'

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.

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

I don't like to compare years, honestly. I think every year is a different experience, a different challenge. You grow. You evolve as a person and as a player.

You can not say you're unhappy because you have to travel, have to play this tournament, having to play sports ... You can't because you chose to play it and you love it. I'm tremendously grateful for the support I have received from my family and the close ones.
