It was quite unfortunate that the two Bundesliga champion has the worst performance ever which is Borussia Dortmund and Bayern Munich, they both lose to a smaller teams they can easily win, actually I don't know if you observed something on today's match because almost all the big teams here and other leagues has a difficulty wining there matches today.
But however of all the matches they have played today, Bayern Munich match was actually what kept me thinking if Bayern Munich deliberately allow Frankfurt to win them or it was there inability to perform well that made them conceive that much.
I am also surprised after having performance like this from the Borussia Dortmund, but things are looking not good for them as they concede 12 goals in their last 5 Bundesliga games which is surely poor from their defense currently they are at the 5th spot which is also concerned for them with we have only two games before long winter break and then next half of the season is going to be more challenging and if they keep going like this surely It's going to hurt them badly and things can go in wrong side as well which is surely not acceptable for the fans and management.
At the top ranks we have few good teams which are going impressive performance and for staying into top four things are tough for all teams now if Stuttgart able to hold Bayer Leverkusen, then surely situation could be interesting otherwise things can go into their favor easily for the title race.
