I had my own youth. I had fun playing in the amateurs, going out with my friends on the weekend, drinking a beer, that sort of thing.

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.

Everyone in my high school was a bit nerdy. We didn't even have a football team.

When I went to high school, an all-boys' school, a Catholic school, I tried out for football, and I didn't make it. It was the first time, athletically, that I was knocked down.

How can we grow the game? It's a conversation in every sport, how do you tap into the millennials? Golf is no different.

My passion is coaching, and I see myself more as a head coach with a more continental approach, in charge of football, running the training programme, the players.
