00:00No, but in the beginning I didn't play my best. I went down 3-0 quite quickly and he started off very, very fast.

00:08I never found a way back in the first set but then from the second set onwards I thought my level raised.

00:15I'm happy with my level then. Today obviously no wind, not really big wind.

00:22It wasn't like that yesterday. The day before it was quite windy so it's just generally nicer to play.

00:28But at the end of the day it's about winning and as long as I'm winning I'm happy.
