was fired 62 days after taking office. German media "Sports Pictures" disclosed some problems between Tenghach and Leverkusen.

reported that Tenghach coach Leverkusen was quickly excluded from the core circle soon, and he kept publicly demanding the introduction of new players. After reaching an agreement on the sale of Zachar within the club, Tenghach publicly expressed opposition, which confirmed the warnings of everyone in the industry that the club could not reach a consensus with him.

Tenhach also did not bring any clear tactical concept to Leverkusen's new team, and no one knew what to do, even if it was a 3-1 lead against Bremen. There was only the individual performance of the players in the game and the overall tactical thinking was lacking. There are still people in the locker room questioning why doing push-ups during training seems to be as important as contacting the run? This is not only a punishment for losing the training match, but also an extremely long training time.
