Hans-Wilhelm Muller-Wohlfahrt stepped down from his role as Bayern Munich s club doctor on Thursday, citing a break in the bond of trust .
Muller-Wohlfahrt, the doctor for the German national team, is renowned as a world leader in the treatment of sports injuries.
In explaining his decision to leave Bayern, he suggested his medical department had been blamed for the club s 3-1 UEFA Champions League loss to Porto on Wednesday, which came with a host of Pep Guardiola s star players absent through injury.
After the Champions League match of Bayern Munich against Porto the medical department was for some inexplicable reason made primarily responsible, read a statement from Muller-Wohlfahrt.
The bond of trust is damaged.
Bayern media director Markus Horwick is quoted as telling Sport 1 that the club had not been informed about this step .
Muller-Wohlfahrt, who has been associated with Bayern for almost 40 years, previously resigned his position in 2008 following a row with then-coach Jurgen Klinsmann, only to return when the ex-Germany international departed the club.
