The larger than life Dutchman says the standard of dressing room facilities at most Premier League grounds means he has to sit on the toilet when his team hit the road
Van Gaal has given a lengthy interview to MUTV in which he looked back on his first season in English football, including United's fourth-placed league finish, and also shed some light on his summer transfer plans.
But while he says he has been very impressed with some aspects of the English game, he has been left disappointed with some of the facilities in the top flight.
"I can say a positive thing and I can say a negative thing," he said when asked about his introduction to life in the Premier League.
"Let’s start with the negative thing. The accommodation for the players to dress themselves, to change into their club shirts, are in most stadiums not so good.
"And also the place for the manager, a lot of times I am sitting on the toilet! But not on the toilet to make something, but because there is no other place. That was, for me, surprising.
"But the way football is lived here in the minds of the people is unbelievable, and it is what I expected.
"I think it’s fantastic to be here in England. They live football, football is living, and living is football. That is not [the case] in Germany, in Spain a little bit more but here it’s unbelievable. It’s fantastic to see."
