Against Nicolas, it is going to be a great match, the one everyone is waiting for. We haven't played against each other in a long time, so facing him here, in Vina, should be a great match.

It was tough. Robby has a great return and he puts a lot of pressure on you when you serve. I was lucky I was serving well and didn't have a break point against me until the second set.

I am a bit tired because the points were really long and you have to run a lot because the bounce is really low. I had a lot of chances to break early in the second set. But the final set I was serving unbelievably and that was the key to the match.

I was prepared for a tough match. In the second set, he started to serve much better. He started to come on and he had me under pressure.

Five days ago I was on holidays at home and I was really having fun.

The court was OK, I guess. There were a lot of people. Everywhere I play I find some fans and it is a big help.

My tennis has been unbelievable.

Five days ago I was on holiday and having fun. Two days I didn't think I'm playing. Now I have a chance to be in the semi-finals. It's strange. Who knows?

He started to make a few returns and chip and charge. He started to come in on my second serve so he put me in some pressure.
