Germany's players reportedly have a number of concerns with manager Julian Nagelsmann's coaching methods after his disappointing start in the national team dugout.
Nagelsmann replaced Hansi Flick in September, but has only won one of his four matches in charge, and his side slipped to back-to-back defeats against Turkey and Austria during the latest international break.
One issue that has arisen already is the players believe he is more suited to club management and is demanding too much from them, according to Bild.
While the mood towards Nagelsmann remains largely positive and the team trust his tactical ability, they want him to simplify his ideas as he does not have the time during short international breaks to revolutionise the way the team plays.
