Bremen has a comfortable gap to place 16 with 10 points. They can actually be satisfied with that. But if I take a closer look, I can see that their last win were 6 matchdays ago against Köln. After that they only managed a drew one time and lost four times. But Franktfurt's performance in recent games has also been very mixed and there is no clear trend to be seen.
If Bremen will lose today and Mainz will win tomorrow things could get exciting again. Especially because many teams in the danger zone are playing against each other this weekend.
Frankfurt will be playing at home and they have a good record when playing at home in the last 5 matches they have played at home they have not lost so I think in the match against Bremen it will be very possible for them to win the match.
On the other hand, Bremen's performance is actually in a very bad state, they have never won in their last 5 matches and also the quality of the Bremen team has really decreased quite a bit in the second half of this season.
For now, maybe Bremen's position is still quite safe from the relegation zone, but Bremen also can't drag on in their downturn, they are only 10 points apart and there are still 7 matches left in this season which means that all possible bad possibilities are still possible for Bremen to face.
