It's hard because you want to be able to just, okay, focus your energy on trying to win the match, but you need to then have tactics as to how you're going to deal with how you're feeling.

I am not anti-English, and I never was.

I was playing in the juniors at Wimbledon I forgot to turn my mobile phone off. It was lying there in my bag and it rang in the middle of a match, and it was one of my friends from school saying, 'Murray, you're on the telly!' I learnt from that. I now put my phone on silent.

Having a normal knee would make life a lot easier.

I had to pay an incredible amount to get insured on it and, after a couple of weeks of driving it around, I realised it wasn't quite my style. I'm not flash by any means but a bright red Ferrari is a definite head-turner and I hated that. It was also incredibly impractical, particularly when it came to finding space for a friend or for my tennis bag, so I decided to sell it after a few months.

It becomes tricky, and you start to think about the cramps rather than just actually what you're trying to do on the court, which is obviously win the match.
