I assume maybe Leverkusen wants to manage young talents like Dortmund did, Ten Hag has enough experience in developing and finding talented young talents, maybe this is one of the reasons why they work with the Dutch coach but for the competition in the Bundesliga I am also not sure that Ten Hag can do the same thing as Xabi, let's see if Leverkusen next season will be as strong as before or on the contrary they will return to being an ordinary team? for now just give Ten Hag time.
With the calibre of signings they have been making it look in that direction that they want to manage young talents. Let’s hope Ten Hag is capable of doing a good job with Leverkusen even if not replicating what Alonso did but coming close atleast, that will be really good for the club and to rebrand his reputation and that has already been tarnished with Manchester United.
