As a kid I was creative.

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

In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.

It was very unusual for a boy to play tennis in my country.

The tradition in Serbia has always been team sports - football, basketball, handball, volleyball and water polo, individual sports are not supported.

I physically feel very fit. I’m very motivated to keep on playing on a very high level. I’m going to try to use these years in front of me to fight for the number one of the world and fight for the biggest titles.

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