It was always a wish for me to work in the Premier League. To work as a manager for Manchester United, the biggest club in the world, makes me very proud. I have managed in games at Old Trafford before and know what an incredible arena Old Trafford is and how passionate and knowledgeable the fans are. This club has big ambitions; I too have big ambitions. Together I'm sure we will make history.

Louis van Gaal has nothing more to learn.

When I buy, I buy players for the long term, not the short term because I do respect the club a lot and also the other clubs.

Running is for animals. You need a brain and a ball for football.

I'm not the kind of coach who just goes out and buys players for the sake of it. I'm a coach who wants to - and can - improve players.

When I think I've made an error, it can cause me a sleepless night. But that only happens rarely.

If certain players do not carry out their tasks properly on the pitch then their colleagues will suffer.
