Striker Luca Toni has revealed former manager Louis van Gaal's unique method for proving he 'had the balls' to drop any member of the Bayern Munich team.
Having joined Bayern from Fiorentina in 2007, Toni, who has since moved to Juventus, was top scorer in his first season as the German club won the Bundesliga title.
But he played just four league games under Van Gaal before he switched to Roma in January 2010 and the 33-year-old claims his ex-boss had an unusual way of proving he was boss.
"Van Gaal simply didn't want to work with me, he treats players like interchangeable objects," Toni told BILD.
He added: "The coach wanted to make clear to us that he can drop any player, it was all the same to him because, as he said, he had the balls.
"He demonstrated this literally (by dropping his trousers). I have never experienced anything like it, it was totally crazy.
"Luckily I didn't see a lot, because I wasn't in the front row."
Meanwhile, Karl-Heinz Rummenigge has backed the under-fire Van Gaal's extrovert methods.
"He is exactly what we want," said Bayern's chairman. "You can't reproach him, he has our trust.
"He's not always a fun guy, or fun to deal with.
"His extreme honesty and openness can lead to friction, but he is an excellent football teacher and coach."
