I'm definitely an all 4 Philly fan and even organized a Eagles bar group for a few years when I lived away.

I do sort of feel like people randomly doing an Eagles chant getting off the subway to walk to the NLDS or in the 3rd Quarter of an Eagles game sort of cringe. Like, I'm used to it, but don't we have better?

This was probably back in 2018, but when I asked some Brit friends in NY, they said Liverpool.

Long standing loyal fanbase and major club in a city with a mix of working and middle class fans. Had some down years, but recently regained success.

Seems to fit well enough with the description with me. But I told them I was going to be Crystal Palace fan since it sounded the most like a strip club.
