I think there are occasional flare ups here. I hear Raider fans can get physical. But o think mostly it’s a cultural thing with European soccer fans. It starts early in life and they take their tribal allegiance seriously. I remember as a school kid in England one year while my dad was on sabbatical, there was this group of kids who would roam the playground chanting “Bristol or Rover?” and if they asked you you had to say who your team was and I was always worried what I was supposed to say, thinking I better pick the right team or I’m gonna get my !!! kicked right here on the playground. Scary.Well I am not saying beating fans of other teams is a good thing. I am not a bellicose guys lol. It just surprises me how visiting fans are comfortable expressing their feelings. I expect at least some quarrels but never saw it.
I actually like that though, especially as I will certainly be a visiting fan of the Illini games after graduation.
