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

My father had never watched tennis, never liked tennis too much. He said, 'OK, we buy a racket, we watch together,' because we didn't know anything. It was a process of learning together that made it more interesting.

In terms of playing ability there is nothing to choose between number one and 100. Instead, it's a question of who believes and who wants it more? Which player is mentally stronger? Which player is going to fight the hardest in the big points? These are the things that determine who is the champion.

The history of our country is cruel. We have to face those issues or, should I say, we had to. Not anymore I hope, because we are going in the right direction, and we are ready to forgive, ready to move on.

Pressure is part of what we do. It's always present.

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

Coaches are very important to players. They're people that are mentors, people that are advising them, people that should be their friends and somebody you can rely on on the tour.
