The change of coach chair that can not be stopped completely and maybe Leverkusen fans are a little disappointed but let the past be the past now in the Ten Hag era there is a sense of doubt for us and there is a possibility that next season Leverkusen will not be able to perform like in Xabi hands the reason is quite simple Writz left and other core players may follow, well here is proof for Ten Hag because by losing some of the team strength of course he must find a suitable replacement and mistakes like at Man Utd must not be repeated because Leverkusen is not that rich they have just risen.
