Louis van Gaal

My conviction is that a full professional also wants to live professionally.

You have to deal with a lot of things when you are a professional football player, and that is not so easy.

I have a philosophy. I was convinced of it, and by winning trophies in four countries, I proved the philosophy worked.

You are always evaluating. That philosophy is very important for me. Because of that, I am - or maybe I should say was - a very successful manager.

Yes, I have a philosophy, and you have to come with good arguments to change that philosophy, but, if someone has a better argument than me, then I will change.

It's a principle of my philosophy that you have to respect the individual human being.

Preparing your tactical formation is essential. Each player needs to know where he has to be, and that is why there needs to be mutual understanding: because you need absolute discipline.

I have good memories of Manchester United.

To look at the players, to communicate with the players, to observe and to analyze - that's my job.

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.

I was a fan of Henk Groot, former striker of Ajax, who scored many goals with his head. I thought, 'I can do that also,' but I couldn't.

Of course I have ambition to become World Champions with Oranje.
