I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

I don't mind fans coming up in a friendly, respectful way. That's all part of the fun of being a top tennis player. But if people take pictures without permission, particularly if my children are in the shot, I feel uncomfortable.

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

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 feel a bit awkward playing in a red shirt out at Wimbledon. But I don't dislike it.

You have to believe in the long term plan you have but you need the short term goals to motivate and inspire you.

The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.
