I wonder how much it hurts you that said lovely club actually helped Dortmund keep its head above water in 2005. And then you'd have to imagine that Klopp's idol was/is Franz Beckenbauer. And on top of that Bayern and Dortmund don't actually have that bad of a relationship for rivals, which isn't that surprising, if you consider that the rivalry means money for both buisnesses. But hey, never forget: Bayern is the bad guy! Despite trying to convince the other clubs to abolish the dumb 50+1 rule, so that clubs with big traditions (for example the HSV, Stuttgart, Cologne, Nuremberg etc.) could get an investor and become competitive compared to Bayern and Dortmund. All just so the Bundesliga becomes more attractive, competitive and all around better, which would benefit all clubs and German football as a whole. Those Bastards!
