Now, Leverkusen is approaching former Dortmund coach Edin Terzic to replace Eric ten Hag.
Edin Terzic is a coach who brought Dortmund to a final match in UEFA Champions League final and also nearly to Bundesliga title in a last season of Marco Reus for Dortmund. Only a very late goal from Jasmal Musiala helped Bayern Munich took over the league title from Dortmund and in Champions League final, they simply were not strong enough to win that title.
Yes, Terzic was a key member of Dortmund from 2018 to 2022, successfully leading them to the final, but they never won it. But well, at least he had some good experience in the Bundesliga. He's currently without a club. However, no decision has been made yet.
The following factors are suspected to be the reasons why Leverkusen sacked Ten Hag in just three Bundesliga matches. One of the most serious is the players' lack of understanding, even during training sessions and matches. This is truly devastating.
