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 need to come back to Wimbledon every year because I can't live without it. I'd be totally cool without tennis.

Having twin girls is a life changer - that's for sure. But I like getting up and changing diapers. It's the things you do.

One or two years ago, I didn't know who I was on court and I used to swear a lot. But now I've learned how to cope and can therefore win 10 matches in a row. I want to be remembered as a good player rather than an idiot on court.

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.

The nicer the point, the more -- the better I feel, the more excited I get. But I never play that my opponent looks stupid. I think that is wrong. I have too much respect for every opponent I play.

With all the injury problems we have in men's tennis at the moment, I'm happy to still be standing.
