Leverkusen just need to play their usual game. As long as they aren't on their unlucky day they should be able to get past Darmstadt obstacle easily. I hope to see as many goals as possible from Leverkusen as well to make up for the last result in the best way possible.

Besides I don't give it much probability but maybe Bayern Munich might get a surprising result against Gladbach considering their near history. If this happens it would be great for Leverkusen. However it is too optimistic to think about this possibility, right?

It's normal to drop point, and besides that, Gladbach is not a small team to underrate, they are not just in good form this season, therefore. dropping points against them is normal and I am still confident of Leverkusen in this season's Bundesliga title.
Bayern Munich might also drop points against Gladbach because when you go through the statistics of their last five matches, you will see a lot of possibilities for Bayern to drop points because Gladbach is always a strong opponent for Bayern Munich, and now that they are looking a way to accumulate some points in order to move up, I don't think they will take it easy with Munich either.
