For much of the year, you're just trying to maintain your fitness. It's not often you get a lot of time to really concentrate on improving it.

Staying more controlled mentally stemmed from taking my fitness more seriously. When you're doing track work, sprints and so on, it's pretty painful, but that does make you feel better prepared and therefore mentally stronger when you're going into a match. You know, without a doubt, that you are strong enough to last.

My fitness trainer's English, my physio's English, some of my friends are English. I don't have a problem with English people at all.

Like most guys, I've always liked watches. I can always check the time on my phone, but having a watch is so much better.

Everyone has to try to give back as much as possible because I think in all sports it helps kids to have role models or people to look up to. Someone like Jess Ennis, I know a lot of young girls have started to get into athletics stuff because of her, because of her success.

A lot of athletes use sports psychologists.

I used a lot of sports psychologists when I was younger... sometimes it helped, sometimes it didn't.

Boxing, mixed martial arts and tennis are the hardest sports to train for.

In tennis, it is not the opponent you fear, it is the failure itself, knowing how near you were but just out of reach.
