That is the challenge and the double-edged sword that Ten Hag has, it is known that Xabi left the bar very high in terms of the required demands, everything would have been ideal for Ten Hag if he had taken a losing team and he turned it around, the difficult thing is to maintain the level and improve it at least they will demand that they have to be in the first 4 places of the UCL classification, for me that is the minimum, in fact they can demand even winning the Bundesliga that is how high I see the demands for whoever takes the mantle for Leverkusen.
The season is yet to start, but I have started to doubt Bayer Leverkusen because of what you just said. Ten Hag needs to make many things possible for Bayer Leverkusen because right now Xabi has Bayer Leverkusen reaching some level, and now for Ten Hag to manage this team, things will definitely be difficult for them because they have already left their two key players to Liverpool, and they have left their manager to Real Madrid again, which means everything will be new in Bayer Leverkusen from the coming season, and things may get difficult, especially in Champions League competition.
