Demichelis spent most of his professional career with Bayern Munich (seven and a half years), winning 11 major titles with the team.
Louis Van Gaal spent two seasons at Bayern when he opted to sell defender Demichelis to Malaga.
The Argentina international had a friction with Van Gaal after being dropped from the starting XI on the first match day in the 2010–11 season.
In quotes reported by Bild, Demichelis said: “I achieved a great deal at Munich,” Demichelis told Bild. “I used my strengths to win a place in the first team.
“I became a fan of the club. I felt like a favourite son. But from the first moment Van Gaal arrived at Bayern the place began to stink.”
Van Gaal won the Bundesliga title and DFB-Pokal and reached the Champions League final during his first season in spite of Demichelis exit.
