Q. Do you think you are unstoppable in the form you performed tonight?
That's it. Just one very good day. That makes me feel confident, but I am in fourth round. That's all.
Q. What are you most happy with in your game right now?
Backhand very good I think. Very good, close backhands. That give me the opportunity to open the court. Then with my forehand, when I able to hit that cross backhand.
And then again today for the first day in the tournament, the forehand down the line worked great. That's a shot that give me a lot when this shot is working. So that's the most important part of my game. It worked well.
If we can add to that, I didn't lose serve during the whole match. That's another good thing.
Q. Obviously the game today is really physical. Do you find it more difficult to get over the mental aspects or the physical yourself?
That's let you play at your 100% from January to November if you want to have the chance to be in the top positions of the ranking.
But most important thing is the health. Then mental part is something that you can control. Is in your hands be well mentally, be fresh, be with motivation. But the injuries is something that you cannot control, so that's tougher thing.
Q. Could you talk about your next matchup.
I need to keep playing the way that I played tonight.
Q. You have played against Kei on all different surfaces. On which surface do you think Kei would be the toughest to play against?
But you can ask him (smiling).
