The increase in their performance from season to season is very good but indeed for this season with the tight schedule they have as well as some lost balance makes the Union not as solid as before.
This season they actually deteriorated especially in defense which I think the change is very pronounced. In addition, their attacking line is also not doing well this season.
It might be a shock for them when they are usually only in one or two competitions but this season they are in the Champions League so they don't look too prepared for that. But precisely when they should prove themselves at this time they are even worse.

You are right, because Xabi Alonso is Growing a lot as a coach and there are many things that can be done to win, and he is also exciting an entire team and its fans to make this genuine football and to be champion of a Bundesliga, I understand what you are saying. When they say that Bayer's dominance can go down, yes, you are absolutely right, but we must also highlight that things are like this because Bayer has made a point of not lowering the level at all. In fact, they know how to move everything very well, both strategists and players , they did everything possible to get their best man, I say their best man because he is the one who has raised the team which is Harry Kane, without him they would be having a very bad time, like that that they know how to do things, with that same order that they have carried out throughout the seasons it can be said that we are people who can see this effort, some see it as dominance, but if a team does not come out that is better ? how to beat them? It has to be on the playing field.

In the Bundesliga they say that it can be boring and for the same reason , Bayer Always wins, but they don't see that Bayer is still far superior, as for Leverkusen I see the joy in their players, the admiration that many feel for Xabi, So these are things that if you are doing well, why are you leaving? Of course it is a matter of "love" that this coach feels for his lifelong team , so on that side I Understand it, because it is already a very personal decision, so I would say that things when they try to do everything better, well, as I said, I Prefer him to be Zisu, but in the case of him and Madrid, things change, I also saw an article where Ancelotti practically approved and wanted him to go to Madrid because he is the perfect substitute, I really want him to enjoy it. for Madrid and if that is the way then things could be quite good.
