Leverkusen have lost three important players as well as one of their best managers and their overall performance is getting worse.
I think that number is not only three... There are even more players who had an important role in team success but left this summer.

Erik ten Hag had a difficult job to do. He made new signings and he just needed time to see whether that would work. But the board were so impatient as it seems...
I wonder what Xabi Alonso would have done in the same situation. Success or failure?
