Probably more like 6. One of us, Chelsea, Liverpool, and Arsenal, or one of the big 2 from Spain. If he was Italian, I'd add Juve, Inter and AC, which all have big followings with people of Italian descent, but don't have as big a catch-all crowd with other demographics. I'm 29, but that just how it was when I was growing up, and the popularity of teams around my college campus which bar was always packed for CL games. No idea if City, PSG, and Spurs have made sizable inroads. Not sure if Bayern has either. Dortmund was pretty much everyone 2nd team though around 2010-2013, where they were no ones favorite, but no one hated them. This is just in my experience in Canada, which I would assume has a similar vibe as the US.
