I just found out that Leverkusen has officially appointed Kasper Hjulmand. I am more familiar with Ten Hag by name, but perhaps that is because his track record is not very good. As for Kasper Hjulmand, I see that he also has a fairly good history, so perhaps he can lead Leverkusen better than Ten Hag. I have also heard that the selection of Ten Hag as coach has been acknowledged as a mistake, and management does not want to make any more mistakes.
I actually doubted Bayer Leverkusen's hiring of Kasper Hjulmand, a manager who hasn't been recognized as a suitable fit for the club, and I worried this would be another mistake. I was initially excited to hear that Bayer would make an offer for Edin Tersic, but it turned out to be just a rumor.
Regarding the mistake of hiring Erik Ten Hag, Bayer should have acknowledged that bringing in this manager could be problematic, but they were simply trying to be confident and now regret the mistake.
