You just try to play tough and focus point for point. Sounds so boring, but it's the right thing to do out there.

For sure, with golf it's not a physically demanding sport like tennis. That's what makes tennis great - you combine both things. It's a very mental sport and at the same time can be dramatically physical. But I do admire the mentality of sport more than the physicality because physical performance is much easier to practice than mental performance.

Is always the motivation to play better and better. But I think we are in a very good way to keep winning matches. That's most important thing for me.

Playing well or playing bad, I have to play aggressive. I must play aggressive.

You have to accept both losing and winning well. I've stayed calm when I'm winning and I've stayed calm when I've lost.

The thing, when you're down two sets to love, is to stay calm, even though it's hard, because people are freaking out, people are worried for you.

My motivation and aspiration is the same, being number one or being number five. So that's the truth. And my goal is the same - it's to always be happy playing, it's to enjoy the game and improve always.
