This looks interesting. Louis Van Gaal: The Biography by Maarten Meijer, out in July.

“If you lose possession of the ball so simply and so often, then it doesn’t matter which formation you play. So as a coach, I needed to change something at half-time. I had to change their mind-set because they needed to play the ball round, and you can do that by means of a different strategy –something to hold on to – and they will have faith and hope. Fortunately it turned out OK, but it could just as well have turned out different.”
