If you want a player to serve and volley more, you need to teach them to do that more, how to move at the net.

I'm a global ambassador for the World Wildlife Fund and United for Wildlife and I am also a Unicef UK ambassador. It's important to me to support charities. I never want to take my wealth for granted.

I guess the closest I came was doing chores around the house to earn pocket money. My brother and I would have to do the washing up, cleaning around the house, walking my grandparents' dog, lots of things. We didn't get a huge amount but it was always enough to be able to walk down to the local shops and get some sweets.

I've never felt nervous in front of big crowds and in big stadiums.

I can't worry about match too much. There's nothing I can do.

Contrary to my image, I do have a sense of humour.

I try to anticipate the ball well. That's something that's helped me since when I was a kid. Just learning to anticipate and read the game well. That's helped me. When I moved over to Spain and I was 15 I was playing with big guys who were 22 years to 28 years old and I was 15 so I couldn't beat them with power. I had to beat them with touch shots and variety and anticipation and all of those things. I learned a lot when I was over there.
