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.
If talking about Union Berlin before this season they have rapid progress in Bundesliga and since got promoted on 2019 Union Berlin can able to improved their position for each years and one of their best achievement is last season when they can able to finish at 4th place and playing at champion league and actually Union Berlin was attempt to improved their squad quality with bought some of new players this but apparently just like i said before this is their biggest mistakes because those players were unable to adapt quickly with Union Berlin and it makes their performance decline and currently they have to avoiding relegation zone but there is still a time for them to survive in Bundesliga and let see whether they can able to avoiding relegation zone at the end of season or Union Berlin will be relegated to Bundesliga 2
