The Serbs feel robbed because of a foul they didn't get and the fact that one of the Albanian-born players of the Swiss team made a celebratory gesture with his hands called the double eagle which is a reference to the Albanian flag and has an anti-Serbian ring to it. Of course there's also lots of conspiracy theorising going on, flags of either nation get burned, etc. In short, the usual Balkan shenanigans nobody has a clue of nor cares for, at least not during a WC.
EDIT:
Whoever thinks that a Swiss ref would be German-friendly just because he himself comes from the German (well, more or less) speaking part of Switzerland (there's a German, French and Italian part) has no clue about the Swiss or Central Europe as a whole.
EDIT #2:
Interesting. Usually it's enough to have one bad boy like Ramos or Chiellini. That could be Boateng. This 10% you mentioned are definitely present within the BVB and it wasn't such a bad idea for them. But it's certainly not the style of play of Bayern Munich, which is the blueprint to our current National Teams. Personally I'm not so sure, but you sure gave us some nice food for thought, Tak.
I'm not necessarily talking about physical attacks but a certain warrior mindset that modern footie schools don't seem to foster anymore. When I was a lad, it was considered normal to throw in your physique as some sort of weapon against your opponent, ideally within the bonds of the rules. This led to a certain roughness of the game which modern spectators probably wouldn't consider good footie anymore but it was effective.
Now, I don't really wanna go back to the Holzhackerfussi of old but I think we could take inspiration from the will to win and no-bs approach of those days when Udo Jürgens sang "ein Fußballstar, der kennt keinen Schmerz, der ist aus Stahl gemacht, aus Eisen und Erz..."...
