I have a very strong opinion. I'm absolutely against it. I'm against the challenge system. I'm for the way it is right now. Don't change that.

No, I'm not (disappointed). There's no reason to be because I'm on an incredible run. You always expect a loss once in a while. So when it happens, why be disappointed if I win over 90% of my matches.

My wife doesn't like Football but she watches it just for Messi.

Being down match point, it's just not fun.

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

One of my big, big strengths I think early on in my career was that I could learn very quickly. You wouldn't have to tell me the things 10 times or 50 times until I would understand them. You would only have to tell me two or three times.

I always knew I had something special.
