Man u, Liverpool and Leeds mainly - big supporters clubs that travel as a group and have done for over forty years now - a lot (most) are much better fans than me. Wolves and West brom with those in their 70s/80s, due to English football being on TV, before Norwegian football was televised. Arsenal are much more popular in sweden, despite having a Norwegian captain and it's just young kids who support man city, because of Braut Håland.
My wife is on a Scandinavian hull city group on Facebook and there's about 30 of us here in Norway, but only one fella and his wife who i know of on my side of the country up in Sogn. This will probably go up in numbers this season. Good bunch of lads and ladies and I went to one of their pub events in Oslo for a game back in 2021(?). One member goes to Hull/East Yorkshire/North Yorkshire/Northumberland every summer with his family. You also get ppl who adopt obscure teams like Tranmere and go over for games.
I don't see them as plastics or glory hunters, just new 'tribes'.
