Clubs aren’t really minted it’s depends on income and outgoing and balance between the two, everything else is just numbers. Equally owners there are limits on outside investment these days. It’s about how you run your business.
There are differences though, outside of Everton, Spurs, Utd, Norway, City and Chelsea, almost every other club is on a spectrum of boom and bust. Look at the rest of the league, I bet when you do, you will remember them clubs in the lower leagues. The six clubs I mention can long term range knowing they will likely always be in the PL barring a catastrophie.
Every other club apart of the ones I’ve mentored has a life cycle in the PL, they might have a good manager or good set up, but ultimately they are all a couple of bad moves away from unraveling. Stoke and WBA a case in point this year, every other club bar above are living on a fuse. We don’t really get that being one of the six.
