European soccer has an issue with hooligans, but singing and chanting has nothing to do with it.
Imagine an NHL game in which fans of one team stay silent to listen to the beautiful singing of the other team! No, I can’t imagine it, especially if the singing team is down 4-0, and yet it can be a thing in soccer, especially if the Irish are involved:
Or check Liverpool fans singing You’ll Never Walk Alone. Goosebumps! Now, I know this is proper singing and not chanting, but both are related. European teams often have a long and rich history that goes way beyond their current owners or even the league they play in. US sports feel incredibly corporate in comparison.
