Even if they continue with Xabi Alonso, their performances might continue to decline and in reality they have more diifculty with a departure of Xabi Alonso, Wirtz and perhaps more star players in remaining days of the summer transfer season.
It has nothing to do of an performances decline to be honest , the other teams and Clubs just made there homework and know how to play against the style from Leverkusen.
All the players and that included the Coach Xabi Alonso also will be not be compensated in the coming season.
It's really hard to believe that Ten Hag will be able to help Leverkusen to perform well and win Bundesliga title again.
Bayern Munich have been back with their domination in Bundesliga and it's unrealistic to imagine any scenario with which Bayern Munich will fail to defend their trophy and also domination in Bundesliga.
I know what you mean about the believe in Ten Hag , but i look with more a just 2 eyes on that , give him a chance as i have written in my previous post.
I dont agree with that , that there was a Bayern Munich domination in last season , it was a few times close that they will be not getting it.
