Leverkusen are really having a bad season at the moment,
Compared to the last years in the German League and without the last season they dont have a bad season at all.
All the other and smaller Teams in the German League just have catched up and learned from the last season how to play against Leverkusen.
For sure there was some games that Leverkusen have played really bad.
Specially yesterday in the DFB Cup they played not good and Arminia Bielefeld was fighting for every Ball.
Congrats to Bielefeld as they deserved to be in the Final
Champions League (Leverkusen fail)
I guess it was not a fail in the Champions League for Leverkusen.
And you cant compare the Champions League with the German League.
