Köln, Mainz and Darmstadt are at the bottom of the table. Things are not looking good for them at the moment. Köln is at place 16 and has an gap of 5 points to place 15, where Union Berlin is. Union Berlin were able to widen the gap with a win against Darmstadt at last weekend. But Union Berlin still have to play their game against Mainz. This was cancelled due to the winter weather. That will be a 6-point game for both teams.
The three teams at the bottom of the table do not have a long distance in points, so in the long season it is still possible for them to recover, but these three teams have not been able to recover until now and even Köln, Mainz and Darmstadt have not been able to win in 5 matches. the last one.
If you look at the overall performance of Köln, Mainz and Darmstadt, I think they have the possibility of being relegated because up to now we haven't seen that they will rise.
