There is no point in predicting that Leverkusen won't make it into the Champions League. They are one of the top 6 teams with great chances to qualify, why would they not? And more importantly, who would qualify instead of them, i. e. beat them in the Bundesliga in 34 rounds?
What happens is that many are speculating due to the entry of Ten Hag , it is normal that they can make bad predictions due to the bad performance he had with the MU, however things are different now we have to believe in the redemption of people, now they have a very good opportunity to do things well with this team even so if they see that the team goes down a lot then they will simply look for another coach, the Germans do not look like the MU that can withstand losing so much.
That is the same for every coach joining a new club, they start from scratch more or less although Xabi Alonso left a good portion of an intact team behind. It's not like all the players left. Losing Frimpong and Wirtz is tough though.
When Xabi Alonso is the colour white, ten Hag is the colour black. That is what I am curious about, I want to see whether someone managing a team like Alonso can be replaced by an egomaniac like ten Hag and still be successful.
