At first, I was sure of Union Berlin because they showed impressive performance and managed to be at the top of the standings for a few moments, but over time they played worse and worse until finally, they are currently in 5th place with 8 wins, 3 draws, and 4 losses. looks like this season will belong to Bayern again.
It was the momentary euphoria they showed at the start of the season. In fact, we see that things have returned to their original form where we see that Bayern Munich is the only team that can maintain their position and sit comfortably in that position without any significant pressure exerted by their competitors.
I think it's not only you who have these thoughts, there are many people who also feel disappointed when Union Berlin is unable to live up to the expectations placed on them.
