In Holland you go into amateur teams, come up through the ranks and are generally spotted for senior or professional football. At 16, I had made it into a men's amateur team, and was picked up professionally from there.

I always watched professional football and my father played at an amateur level, but I didn't think I wanted to become a pro.

I don't regret writing my book at all. I wrote it for the United supporters to give them a proper insight into what it is like inside the club, and what it is like to be a Manchester United player. I think I did that in an honest way.

I think that's one of the most important thing for a player to have - to have goals for yourself, that you want to make steps, that you want to improve yourself, that you want to go the highest level.
