Since Erik ten Hag has been in charge of Manchester United, Manchester United has been doing poorly and at one point Manchester United was forced to sack him, so naturally he has a negative reputation in the transfer market, but we can see that Leverkusen has appointed Erik ten Hag as their team manager. I really don't understand why Leverkusen handed over the responsibility of their team to ten Hag when there are so many managers. It is said that one of the architects of Manchester United's destruction is ten Hag, now he may work with Leverkusen again and it may be that under him Leverkusen is ending the season with the same bad results as Manchester United.
Manchester United and Leverkusen are in a completely different situation. Manchester United's decline cannot be blamed solely on their coach. Their management has a role to play in Manchester United's decline. Also, the bonding between the players was weak.
However, I also think that Leverkusen could have taken on someone more experienced if they wanted to. Ten Hag's biggest failure with Manchester United was that he bought several players at very high prices. And Manchester United wasted a lot of money. However, he cannot do that with Leverkusen. Leverkusen will not create a large fund to buy players. So Ten Hag will have to try to strengthen this squad.
Ten Hag was quite successful with Ajax. And this is probably why Leverkusen gave ten Hag the responsibility. The situation of Leverkusen and Ajax is very similar. So Ten Hag has a chance to succeed with Leverkusen. Manchester United had a lot of star players. It was difficult for Ten Hag to manage star players. Ten Hag will not face such problems at Leverkusen.
Ten Hag entered a club at United where "structure" was only an suggestion. You had PR consultants, retired legends on WhatsApp, and a transfer committee giving €80 million on players
Leverkusen has a distinct structure, sometimes even overly rigid. Their model is sustainable seller: develop, shine, sell high, repeat. Their salary-to--revenue ratio (18%) is shockingly good compared to the Bundesliga average of 55%. You believe they would let Ten Hag spend like a drunk CEO at Old Trafford? He is inheriting a team drilled for Xabi-ball, full of specialists like Grimaldo and (for now) Wirtz, both of whom suit systems rather than ego fights
Regarding experience, they could have gone for a well-known name but what would that solve? Leverkusen's past season was a perfect storm: an organised team, tactical cohesiveness, and a manager that really matched the club's philosophy. Ten Hag at Ajax worked since the setting was controlled, youthful, and open to learning. That represents more Leverkusen than United. But this is the Bundesliga. The man will have to make Mukiele looks like Frimpong and hope Buendia becomes Wirtz over night. If he manages to do that? Statues, parades of streets, the works. If not, then Leverkusen will still be profitable at least
