https://www.mirror.co.uk/sport/football/news/manchester-uniteds-louis-van-gaal-5893628When Louis van Gaal famously dropped his trousers in the Bayern Munich dressing room his players were distinctly unimpressed.
Van Gaal committed the outlandish act to justify his decision-making and show he had the ‘cajones’ to make tough calls.
Mark van Bommel, who was Bayern captain that day, mischievously indicates with his forefinger and thumb that Van Gaal’s stripper act left much to be desired.
But the former Bayern and Holland midfielder believes Van Gaal will ultimately bring success to Manchester United, despite a difficult first season in charge at Old Trafford.
Van Bommel, speaking at a legends game between former United and Bayern players at Old Trafford, recalled the moment Van Gaal exposed himself to prove his managerial boldness.
“The German players didn’t understand what he meant,” said Van Bommel. “He changed two players after 55 minutes and he wanted to explain why he did it.
“He was searching for the right words and his explanation was he doesn’t change for change’s sake. He thought, ‘I have an idea’.
“Afterwards, we were laughing and we were doing it in the dressing room as well.”
Recalling the incident himself some years later, Van Gaal said: “I once dropped my pants in front of the entire squad.
“I wanted to make clear: When I make a substitution, I don’t do so for my own ego, but for the sake of the team.
“I do everything for the team and I use everything I can to illustrate that. My voice, my mind, and everything else I’ve got. This shows the strength of our team sprit.”
