Is there a generic Spurs, Man U, Arsenal fan that I’m unaware of?
The answer to this is definitely “yes”. In normal times, they’re found in your local pub on a Sunday afternoon wearing the latest polyester offering of their chosen club and shouting loudly at a screen that can’t hear them. They may also ask you who you support and when you reply “Scunthorpe”, they will ask “do you not support a big club too?”.
Again, sweeping generalisations. Of course there are premier league fans like that but there are many others who aren’t. I know a number who are born and bred Liverpool, Man U and Spurs fans who are not like that at all. I’ve met many on trains on the way back from Scunny matches over the years and I’ve not met one like that. If you want to laugh at those fans in the pubs you mention fine, I get that, but for every one of them there is a decent supporter.
