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.

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.

I want the same thing I've wanted since I was 7 years old. I want to be No. 1.

People look up to me as somebody who is able to switch the image of our country from negative to positive.

I want to help children in Serbia and around the world so they can realize their dreams.

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

I embraced, I think, the process of becoming No. 1 of the world, which was long and difficult, but it's sweeter in the end.
