They just faced 5 teams in the bottom 8 and picked up a total of 5 points, they just gave up 5 goals in 21 minutes in a complete capitulation and once they hire a manager for the 23-24 season, it will be four different managers to start the last four seasons (Jose in 20, Nuno in 21, Conte in 22, new manager X in 23). They finished fourth last If that's not crisis, I don't know what is.
Clearly money isn't everything otherwise ManU would have more than 2 top-2 finishes in the last decade in the league. Of course there's Man City on the other side of things.
I'm not delusional to think that Spurs should be challenging for a title pretty much ever. That there was even any talk of that coming into this year was nothing short of ridiculous. But I don't think it's crazy for them to be competing for top-4 year in and year out. They do spend less than the other big teams but they're not that far off in terms of player salary (it's really the last couple years the top four has put some distance between them and Spurs). I looked at transfer fees but just looking at those year by year doesn't seem super helpful (this year Spotrac has West Ham in third, Forest in fifth and Man City in sixth).
