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.
The fact that Bayern u lost at home even gave more credence to the victory borussia Dortmund got over them over the weekend because normally we would expect that the fact that Bayern Munich will be playing fr home is enough reason to think that Dortmund wouldn't be able to get victory over them moreover according to the history on paper, Dortmund has always found not difficult and has not won Munich over five years.
For Dortmund it was actually a breakthrough because they had to terminate a very Long time record by winning Bayern Munich and it's actually now looking like this is one of Bayern Munich's most vulnerable State in a season they have ever been before because the losses they are getting at this point is just in usual and at some point they will get a landslide victory over other teams and it will look like they are back in form again and the cycle continues since this season,they have to work on been effectively consistent despite been at the second position on the table.
Bayern can only get back to glory ways probably by next season but for this season they have been really messy and have really not gotten productive enough even though they started well they are finishing in a poor form and it will be fair to say this is one of their worse season ever in the bundesliga but hopefully they are definitely going to fix it the only problem would have to be that their Coach may likely loose his job this season.
