Union Berlin are lucky to be outside of the relegation zone and that's the best thing they could achieve this season. Being beaten by Leipzig is a normal result for them since Leipzig is a way better team than them.
Yes they are lucky for the moment to be out of the relegation zone for now , but compared to the last season , its very disappointing how they are doing.
And the season isnt over now and its only 2 points to the next relegation place , and i guess they have to fight all the games to stay alive.
In this round, Borussia Dortmund lost two points against Heidenheim which is unfortunate for this team since they made the gap between them and Bayern Munich go up to 13 points in addition to letting Leipzig being near them and threatening their Champions League spot.
Bayer Leverkusen and Bayern Munich in the other hand are continuing to dominate the league with as low as two points difference between these two teams.
I dont think that Dortmund have not real chances to get the title anymore and that they will be try to get at least a spot for the Champions League.
The title race will be this time between Leverkusen and Bayern Munich , hopefully Leverkusen will get it.
