I would still say it's a positive result for them considering the fact that they have been mainly off in previous games. Also the fact that despite their bad season so far the difference from their stand point presently and the top 4 is really not that big, 6 points and of which they can recover it if they maintain this their new form.
Dortmund have dropped a lot of points in their poor games and although the gap between the top 4 is not that big the amount of points they need to catch up on is not that big, but if Dortmund are not consistent then it is impossible to achieve that result. If they want to qualify for the Champions League then they have to recover from the poor form they have been having and in the next games they have to be much more consistent. I think it is difficult for Dortmund to catch up on the top 4 because they are in 10th place even though the gap between them and the fourth position is not that big.
