I would say you Americans are more into gambling while in Europe fan violence is a bigger topic. Like just last week, after PSG won the Champions League title, there were cars burning in Paris:

Honestly this is why i stopped playing and watching any soccer. Every match the city would turn into a fortress and still there would be regular riots, the game seemed to have taken second seat and its more about whats going on around it. Even when games got cancelled because of violence in the stadiums, the ‘game’ would continue outside (violence). So tiring, boring, destructive, terrible.
