The way Union Berlin started this season, many thought they would continue to challenge for the title at the end. But now Union Berlin is fifth in the points table. Their performance is very poor. They have won just one and lost three of their last 5 matches. They are 7 points behind Bayern Munich. Union Berlin has no chance of challenging for the title. Also, with Berlin's current form, it is very difficult for them to qualify for the Champions League. Unable to return to form, Union Berlin will not be among the top 4 teams in the table.
The decline in Union Berlin's results was expected, they do not have such a strong team to fight on equal terms with Bayern for the championship, and even more it looked difficult, since they still play in the Europa League. Not all clubs that have money and a full-fledged bench are able to play in two tournaments, and this would be even more difficult for a club like Union Berlin. Perhaps they should have focused on the Bundesliga and their chances would have been better, but they decided to move in bouth tournaments and it is clear that their results have deteriorated.
