In terms of quality it might be much more difficult for Darmstadt to beat Dortmund and I also don't see the match ending in a draw with the quality of players available. So realistically I see Darmstadt's chances in the next three matches will be much more difficult to get points because they face much stronger teams.
You are right on that , that it will be difficult for Darmstadt to get an or any point out of the next games.
But on the other hand we have seen that Dortmund making some bad surprises , specially against such teams we think they win them.
With what Dortmund has played some matches the last weeks its possible to see some unexpected result.
My bet there will be for sure on the win for BVB.
