These lists are silly because everyone uses different factors to judge how big a team is depending on the club they support.
For some total trophy count will be the sole defining reason, typically fans from historically big clubs like Everton etc will use this as the definition for bigness as it allows us into the conversation despite the fact we haven’t won anything for twenty odd years. The fact is though that there is an entire generation now who view us as complete no marks who are here just to make up the numbers... so long as never win anything in younger generations lifetimes we will continue to be viewed this way.
Youll then have other clubs who have no history of winning trophies who think they should be in there purely because they have fantastic attendance... see Newcastle. This is delusional.
Ultimately for me it has to be a combination of total trophies, recent history of success, current attendance and worldwide fanbase. With those things in mind I think we place about 7th.
There is no way in hell we’re bigger than Chelsea nowadays. They have been near top of English footy for the past ten or so years and have developed a significant worldwide fanbase.
City are a bit different. Historically they are not a big club, same goes for Chelsea but they are winning trophies now at a time when the sport and premier league is bigger than ever. They will grow massively as a club over the next decade or so and most likely end up on similar level to Chelsea in terms of popularity.
Spurs I kind of view the same as us, good history of winning trophies but not enough success in modern times. They do have a bigger fanbase though but that’s to be expected given the size of London. Sure they haven’t won the league as much as us but they’ve won lots of FA Cups back when that was considered a very big deal.
I think 6th/7th is fair enough.
