My nutritionist has done a great job in changing my diet after we established I am allergic to things like gluten - I can't eat pizza, pasta and bread. I have lost some weight, but my movement is sharper and I feel great.

Mangling my racket and an odd swearword on the court is not something I am proud of and it shouldn't happen, but even my coaches have told me that it's sometimes better to let it all out, the anger inside you, because keeping it bottled would just eat you up in the long term.

I love football and it's the sport I would really like to play. I've said on national television here that I would really love to play for one of our football clubs when I finished my tennis career.

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.

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.

We have a harder way to succeed in life as Serbs because of the past that we had and because of the history we had.

In my case, I can sincerely say that nothing is impossible... When I was saying I want to be No. 1 of the world, and I was seven or eight years old, most of the people were laughing at me because it seems like I have one percent of chances to do that, and I've done it.
