When you have the ball above the net height on grass, it's easier to play, and when the ball comes at you more slowly, it's easier to play. But when a guy hits hard and deep, I think you have to have been out there playing to understand, but it's hard to really hit the ball.
I do a lot of conditionning in the off season with my coach but there a lot of exercise and they are specific to each individual.
When you play against Roger, it's always special. First, because you play in a big area, in a big stadium anyway. And every time the crowd is for him, so it's quite a good sensation.
I get some letters from a lot of people. Sometimes it's nice, with letters from kids or from parents of kids who want to be tennis players, but I also get racist letters. It's really painful to receive something like that because you're not ready for that. You think to yourself, 'That's really bad.' But I realise that there are people like that.
I think my best friends are my team-mates in Davis Cup. We have been growing up together since we were 11 or 12.
When you play a big server, you are under enormous pressure on your own serve because you cannot afford to be broken. That causes a lot of players to panic: you see double faults or tentative serves. It's all in the mind, but it still happens.
I hope I will have a family. A house, with a garden, will be nice. And I would love a barbecue! Just very simple things and a passion to work hard.
