I was struggling to find the right shots and was mis-hitting a lot of balls - I'm just glad to get through in the end. To play a match after winning against Federer was always going to be difficult mentally. It was really tough because there was no pressure against Federer and today I was expected to win. Davydenko is a tough match, he's been in the top 10 for the past few years but I've got a good record against him.
