This whole "only respect teams who were big" argument is retarded. By that logic there would be only a couple good teams(if not only one) per league. No competition whatsoever. That Bayern fan can be no older than 15 imo, he's probably just really started following football a couple years ago and is still in that learning about history phase. And we all know how the past is blown up and makes teams to look as noble and dignified as possible.
He'll grow out of it although there's people in this forum who still think like that. They need to learn it's a business first and there's nothing wrong with other teams succeeding, even if the only way to achieve that is by massive funds. That's one thing where American sports are way above football. The federations try to be as fair and possible and provide an even playing field for all the teams, unlike those corrupt fucks Blatter and Platini.
