You have to believe on the court. In the end, it's mental. In these moments against a great champion like Rafa, you have to believe. It's all about stepping in and taking your chances. I always believed, but it's a process of learning.

I always try to adjust to the situation.

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

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.

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.

I always try to have something that keeps my mind relaxed, keeps my mind a little bit off tennis.

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