I suppose you are right on that, one can even call it as an over confidence on the team and their fans. You know when you have become good with something that always favours you, you then take it as part of you and feel everything is actually going to fall into place which obviously is not so because life and football itself can be funny, I could say what happened to Bayern Leverkusen was a typical example of how life actually plays or hits someone.

for me or even for all football bettors and fans, the Leverkusen incident is very clear evidence that no matter how strong the team is and no matter how strong its consistency, in the end there will be another team that is much stronger that can beat it, like Atalanta who initially underestimated and even considered not the favorite team, but in the end the team bought all their doubts.
and it is a valuable lesson for Leverkusen and even bettors that everything that looks convincing does not always produce something beautiful and this is also one of the lessons and experiences of Xabi who became one of the great coaches in history who was able to conquer the Bundesliga even though he had to fail in the Europe League but in the future Xabi will definitely have a better strategy.
Leverkusen failure is a source of pride for all parties involved, even though they could not get the title, but as a team that only lost once in one season, it was something very big and they even managed to get the DFB title which could replace the European League title this season.
In the following season Xabi will still be the coach who will manage the Leverkusen players and it is possible that Xabi will have a slightly bigger challenge to compete in the UCL to prove that Leverkusen can be part of this big team.
