Of course it was emotional. But the fact they felt they had to 'settle the score' with the refs after it was all over, and pointless to boot, showed their lack of ability to rein emotions in with time and to 'pack it in' when it's over. Do you think people feel the need to point out the Uruguayan behavior as a disgrace because they see it all the time and it's a nothing burger? Obviously not. It's something most people not exposed to Latin American football would rarely see. The fact your example, not even directly comparable, involving Chelsea shows a 13 year old match that people will probably talk about for decades is actually proof of just how unusual this would be in Europe.
