I had set a goal with my team to try and get back to the top of the rankings, but I never thought with the depth in the game this year that I would have been able to get it back so quickly.

My family is the thing I miss most on the tour.

The serve, I was too young and too small and... not enough powerful to have a good serve when I was young, so my forehand was always my signature shot. So I used to always run around my backhand, you know, use my forehand as much as I could, and so that's why I think it's my strength also today, you know.

I have to fit holidays around tournaments, particularly the grand slams, in Melbourne, Paris, London and New York.

I always believe if you're stuck in a hole and maybe things aren't going well you will come out stronger. Everything in life is this way.

I think it's very hard for coaches to work with me. They'll no doubt have a good CV afterwards, but at the same time they're under a lot of pressure.

I can walk around screaming, 'I have 17 Grand Slams. I have the record here or there.' When you can play for history and you do it, that's what is so really cool, is that you can then be compared to other greats or you've passed another great, even though it doesn't mean you're better than him. But it's just like that moment you've gone into the unknown where nobody else has ever been before.
