It was an extraordinary victory for Borussia Dortmund, they didn't think they could beat Munich at the Allianz Arena stadium, even though it was quite a difficult match for the visiting team, but it turned out that Borussia Dortmund was able to do it well and steal the full three points from Munich, making Munich even more frustrated because they had to suffered defeat for the umpteenth time and made the distance with Bayer Leverkusen even further away.
That's right, luck was in Dortmund, even though when you look at the total number of shots and the performance they had it was clearly superior to Bayern Munich, but in reality Sven Ulreich couldn't protect Bayern Munich's goal from the shots given by Karim Adeyemi and Julian Ryerson. It seems like there is an internal problem being experienced by Bayern Munich so that their strikers cannot defend against Dortmund and have poor performance.
