I think you mean ADHD. I suppose it is a possibility because sufferers often tend to act the clown in order so seek attention. However, while I agree that the Tour could do with some lightening up, I think it's sad that his widely acknowledged great tennis potential often suffers as a result.
Yes I might mean ADHD! He definitely has potential but as he doesn't like tennis he can't put his mind to it. He's earned lots of £££s along the way, he might be happier doing something else.
He likes basketball, he might like cricket ?? lol
