Let me give you a broader perspective: Barca has been seen in Germany as a great traditional club, one of the few beacons of hope against sportswashing clubs etc. Sruff like the UNICEF "sponsoring" guaranteed a lot of respect and good will, the excellent football aroun 2010 definitely let this respect peak.
The arrogance, delusion and disgustable behaviour towards their own players destroy this image in record time. It's not about our league being boring, it is about losing hope that good clubs have a chance to win the biggest honors.
English teams haven't been proper clubs for ages, Real Madrid has never been likable, Atletico is a bunch of dirty cnuts, Bayern is respectable but not likable, for PSG see English clubs and thats about it who might win the CL... Barca was kind of the last potential CL winner that one could like.
Now even Real Madrid looks much more like a true, nice team. A decade ago I could have never imagined to react to a Real CL win with "nice, the old boys did it once again"
