Why not choose both as a parlay bet I think this is a good opportunity to make a profit although the odds are low, the risk is also low. Bayern Munich and Leverkusen are both targeting 3 points in an effort to maintain a position at the top of the standings and one mistake will disrupt their strategy that was built from the start of the season. Previously Leverkusen had missed 2 points while playing with a draw and let Bayern Munich to get closer, if Leverkusen makes the same mistake, Bayern Munich will take over the standings.
Borussia Mönchengladbach beat Stuttgart and drew with Bayer, so this is not an easy opponent, and given how low the odds are for Bayern, the risks are not worth betting on Bayern today. For Bayern, today's victory is very important, but this does not mean that it will be an easy victory for Bayern. Bayer today has a much weaker opponent, with such a poor defense Darmstadt has no chance against Bayer.
