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.

In tennis, because of the way it's scored, I don't think that scoring one point out of luck is ever decisive in winning. But, of course, it depends on the moment.

For me, that's the most important thing, feel myself happy when I am playing. If I am healthy and I feel myself competitive, I am happy. Then is obvious I would like to win. But I know if I am in finals of important events, the normal thing is I finally win titles.

Most important thing, I am not a player who win the serves because I serve aces or free points, no. When I winning a lot of serves is because I am playing well from the baseline. That's why.

We'll try and be very aggressive, we'll try and speed up and change gears, and we'll see who's going to win.

The only way of finding a solution is to fight back, to move, to run, and to control that pressure.

It's more a tennis problem than a mental problem. The transition is difficult. It depends how much time you have. Playing on grass can sometimes be a bit of a lottery.
