Let's look at the bottom of the table occupied by Union Berlin. They are in the Bundesliga after being successfully promoted in the 2019/2020 season, as a promotion club, their performance can compete with clubs that have been in the highest caste of German football, even they can compete in the middle of the table, and in my opinion it is something very extraordinary. More than that, even they can improve their position every season and the most recent is when they can finish in the top 4 last season. Now they are at the bottom of the table, it is a very significant decline that they show. with their experience of rising from the second caste, they should make it a motivation to be able to rise again.
I don't know what actually happened to Union Berlin this season, even though in the previous season they performed very well and even managed to finish in 4th place until the end of the season, just imagine, when they faced Leverkusen a few days ago, Union Berlin's performance was very bad, they were only a little able to get the ball
While Leverkusen continues to show their best performance, they are even able to stay at the top until now with a difference of 2 points from Bayern who are in 2nd position, it seems that a derby competition is taking place at the top of the Bundesliga standings
