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.

Louis van Gaal has nothing more to learn.

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

I am who I am: confident, arrogant, dominant, honest, hard-working and innovative.

A system depends on the players you have. I played 4-3-3 with Ajax, 2-3-2-3 with Barcelona and a 4-4-2 with AZ. I'm flexible. The philosophy stays the same though. I don't think that you can adapt it to every possible situation. You need the right mindset, and it depends on how the players see the coach and vice versa. The coach is the focal point of the team but you need to have an open mind, and so do all the players. Everyone needs to work together to achieve a common goal.

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.
