As for the rest, as I said, it might be that it's their sucess that evokes antipathy in European football fans, although I do feel Barcelona wasn't as unpopular back in the day as Bayern are today. I hear a lot of people say they are arrogant. Whatever it is, t doesn't really matter. For me, personally, it's Uli I can't stand, along with the things I associate with Bayern (justifiedly or not), which I have already talked about at length. With a different management and perhaps a slightly different philosophy, I could like them, since I have nothing against their players or the regionalism they embody as such (although I'm not especially fond of Bavaria).
Yeah, I remember that game. It was an exaggerated story by Großkreutz, that's nuff said really. Other than that, I think they deserve nothing but admiration for their activities on the transfer market, which have been brilliant year in year out; they deserve nothing but admiration for that. Also, how they've emerged from a low-class, low-budget mid table club to an European force is nothing short of amazing.
Well, the thing that bugged me about that incident was that Großkreutz was not just "exaggerating", but the whole team started making up things and lied to the camera without blushing. They were dead serious about that incident, like it actually happened. I call that a serious lack in character. When you are a public figure and are in front of a camera, you simply are not supposed to lie through your teeth. These guys are football players, not politicians ffs.
Also the "Echte Liebe" slogan always bugged me, since it implies that only BVB fans can have true love towards their club, whereas the loyalty others share with their favorite team, is somewhat insincere in comparison.
"Mia san mir" is much less imposing on the feelings of others, since it merely states that "we know who we are and we like it, no matter what everybody else thinks or says". Such **** off mentality often serves well in real life btw.
However, as you said, there is no denying the accomplishments by guys like Watzke, Zorc and Klopp, rejuvenating a club which was facing financial death (which could be thwarted also with the help of Bayern
) and was close to its last breath and turning it into a national (double) champion and a real contender on the international level within just a couple of years. For that, my hat is off.
Bayern on the other hand... I dunno, it's difficult to grasp how international fans would get the idea of Bayern being arrogant. I think it's more a matter of BVB being the supposed antithesis to Bayern and also the underdog, when they squared off in the CL final. And people just love to support the underdog and hope to see them win, no illusions about that. So in that instant Bayern was immediately labeled that big, bad wolf.
Also the sheer dominanting fashion in which that CL trophy was eventually won (remember the Barca and Juve legs as well as the first leg against Arsenal), caused a lot of hate. You just don't like to see you favorite team getting thrashed and humbled like that. It's humiliating. And you can't expect people to love the big bully afterwards.
