It won't be nice if Bayern Munich give Leverkusen the opportunity to win. If Leverkusen win Bayern Munich I think fans will be disappointed in Bayern Munich for them to still continue in their weak performance.
I still believe Dortmund will defeat Koln.
Bayern München will play on Friday after international break. Will this have a negative effect on them? I think Bayern will win no matter what because Bayer Leverkusen is in a very bad shape this season. Normally, they were a team that pushed Bayern, but with this form, it's very difficult for them to get points from the match. Very low odds for Bayern München win though, it might be better to play over 2.5 goals bet.
It's unclear what Borussia Dortmund will do against Köln. They are favorites in the match, but they are playing a difficult away game and they still have striker problems, Haller is still unavailable. Still, a high odds bet on a Dortmund win can be tried. But I would say don't trust them too much.
