The moment Ten Hag was hired was when I noticed that Leverkusen are confused on which coach to hire and how they can maintain the team performance. Imagine, what do they expect, a miracle or something more than a miracle. The way that you lay your bed is how you will lie on it. Leverkusen sold their best players and hired Ten Hag. What do they think the performance of tje team will be like.
Several managers with even better reputations were also available for free, such as Xavi. I'm honestly also surprised by Leverkusen management appointing Ten Hag as Xabi Alonso replacement. Additionally, seeing them release most of their key players in one transfer window, I think Leverkusen management wasn't serious about maintaining their existence as one of the elite teams in the Bundesliga. All the fans worries seem to have come true, so far Leverkusen hasn't been able to secure a single victory.
