The departure of Xabi Alonso was indeed a regret to the club and hiring Erik Ten Hang as the head coach was the mistake then firing him was actually the exact way to correct it and now hiring Kasper Hjulmand is the wise decision to take, I strong believe he will bring back the team to it winning ways, I'm not really expecting a performance like that of Xabi Alonso but hopefully he won't disappoint, he's kind of play tactics and formation will definitely set back Bayern Leverkusen to their normal state, rather than that of Erik Ten Hang, like I really believe he can handle the job well.
First of all it was never the intention of Bayer Leverkusen to let Xabi Alonso leave the team after helping them to win the league but when happened was beyond their control so they couldn't stop him, Ancelotti was leaving the Real Madrid team so they contacted Xabi Alonso you don't expect him to reject the biggest team in the world when most players are rushing to play in Madrid. Leverkusen should have waited a little instead of going for Ten Hag but now that he's no longer there
Kasper Hjulmand should try to do better.
