People have a different impression sometimes because of the way I'm on court, but outside, I'm nothing like that.
When I come to London, it is always quite relaxing for me in a way, not just because it is one of my favourite cities but because it comes immediately after the French Open, which for me is a very significant tournament with lots of pressure.
You can't really hit on grass. There are lots of bad bounces, so when the guy plays deep into the spot where the grass has been worn down and he doesn't leave you the time to play, you don't have time to play fast yourself.
