Serdar Tasci has admitted that it was a mistake to join Bayern Munich.
The 28-year-old arrived at the Allianz Arena on a six-month loan deal from Spartak Moscow in January.
However, since then, the defender has made just one senior appearance for the Bavarians.
"If I had known that I wouldn't play, I wouldn't have done it," Bild quotes Tasci as saying.
Tasci's only outing - against Darmstadt 98 in February - lasted 53 minutes.
