I honestly do not think that Bayern Munich is going to face any problem, trying to beat Koln in the next match. They are currently in fairly good form and I don't see how they might actually be able to lose in this match. If anything they are going to be very determined to get all the three points from this match because they need to compete for the title. I don't think we have recently seen them be in the second position, consistently for such a long time in a single season. if I were Bayern Munich, I would have taken Leverkusen very seriously.
Before the match with Bayer, Bayern still have to play with Stuttgart, and if you consider that they were able to beat Dortmund, then Bayern should also take this opponent seriously. Bayer have already proven that their intentions this season are very serious and they will try to become champions, if they can do this then I will be surprised, not many teams can go through the whole season without any slumps, if Bayer succeeds in this then they can become champions.
