Former Manchester City defender Martin Demichelis has branded Louis van Gaal as "loco".

Demichelis worked with the former Manchester United manager at Bayern Munich.

He recalled to La Nacion: "He's a good coach, but completely crazy.

"Sometimes he would go over the top.

"One day, we were winning 3-0 and at halftime he entered the dressing room screaming and knocking on the doors, saying that we had been a disaster.

"As a second captain, I tried to stop him, in the second-half I was not quite right and then he told me that he had been wrong because he had unbalanced me emotionally, and he also asked me not to get into his speeches."
