It is worrying to see Union Berlin at the bottom of the table, they are the club that has suffered the most defeats with 9 defeats recorded. Last season they were a club that could compete at the top of the table and they were actually very troublesome at the start of the season. But when entering the new season, they lost everything they showed last season. Losing several players is one of the reasons they have declined so much, and at the same time other clubs have improved.
The next match they will host Monchengladbach, I'm not sure they will be able to win.
Union Berlin topped the points table for a long time in the previous season. They played very well last season. Because of this, fans expected a better performance from Union Berlin this season. But their performance has been very disappointing this season. They are performing badly in every match. And Bundesliga qualification is unlikely to be achieved by this team. They have won only two out of 12 matches. I can't remember the last time this team won. It will be difficult for Union Berlin to win against Gladbach. The gladbach team can be considered as the favorite in this match.
But at least, Union Berlin still has a chance to get out of the relegation zone, because the closest teams also have results that are not much different from Union Berlin. But indeed, usually these middle teams like Union Berlin when they managed to have good results in the previous season, then teams like this will be easy to fall in the next season and that happened to Union Berlin at this moment. Maybe indeed, because of Union Berlin's success in the last season too, then at least Union Berlin's key players then left and or there was no good management to maintain their performance. So yes, it seems that events like this sometimes often happen in every season about different teams and leagues out there.
