I am very sad that I cannot go to the Australian Open to defend my title. I have been working very hard and it is a lot better.
There was so much wind, it was tough to play good tennis. I'm having trouble getting my confidence back. But I'm working hard and trying to do it.
I have been working very hard and my knee is a lot better but it would not be right to go to a Grand Slam and test my knee right now. I am sorry to all my Australian fans but I will be back next year.
If I can put pressure on his serve, I'd have a chance. It's going to be very hard because he has been playing amazingly.
It is very hard for me to switch from clay to grass.
