I'm not allowed to make a joke. It is a bit unfair how I'm treated. I thought it was a joke. I got calls and messages. I would rather not to have to worry about things like that. It is disappointing.

This will be my first Grand Slam final without Roger Federer or Novak Djokovic on the other side of the net, but I don't think being the more experienced player will make much difference to my approach.

I've been asked a lot lately if tennis is clean or not. I don't know any more how you judge whether a sport is clean. If one in 100 players is doping, in my eyes that isn't a clean sport.

Having a normal knee would make life a lot easier.

Every week I'll be spending money on flights, accommodation, stringing and even things as simple as taxis, meals out and, of course, paying the other members of my team. I'm still very careful, though, with what I'm spending.

There's no doubt Milos Raonic will be a very tough final opponent, after all he beat [ Roger] Federer on Centre Court to get there.

I listen to my iPod as I walk on. If I'm winning I'll listen to the same song, that's like a good luck thing - usually The Black Eyed Peas' Let's Get It Started.
