Football's the big cheese, if you like. It's easy to have a swipe. There's a lot of footballers, and when they fall foul, they become big news.

I think medically, football is generally well looked after. There are always checks made. Anything which can be done to make footballers or sportsmen of any area safer has to be encouraged.

I was quite good at football once, although other than that my speciality would be maths. I'm great at sudokus and find all the spin-off games pretty easy too.

Most clubs would actually like homegrown players because they're a lot cheaper.

Fundamentally, footballers don't look around a dressing room and think, 'He's a black player... he's Japanese.' They don't think like that. They think, 'He's a good player; he can help. He's not very good.' I'm not trying to defend anyone's actions, but there are going to be isolated incidents because it's an emotive, passionate sport.

Diving is a really, really difficult one because a player is the only one who genuinely knows whether they have dived. You can look at it at 40 different angles and not know. And you can just fall over, too.
