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?
I'm curious to witnessed the first team to break the unbeaten run for Bayer Leverkussen this season. Bayer Leverkusen draw their previous game, a good path for the club to fight for more significant points to accumulate in next game, definitely against Darmstadt. Bayer Leverkusen is a top club, they don't perceive Darmstadt to become a threat for them because they have everything within their reach to win matches. Xabi Alonso will probably skip these games and focused on the main threats because he's side have chosen not to lose now.Besides I don't give it much probability but maybe Bayern Munich might get a surprising result against Gladbach considering their near history.
