Where would they be now if they didn't have us as their neighbours? Still in the same mess?
I won't pretend to understand all the financial details, so maybe they were screwed from the moment Moshiri got his claws in them. But if they had taken the time at the beginning to build a Brentford or Brighton-esque structure behind the scenes using his money, and then judiciously spent that bulging transfer kitty on carefully scouted, Moneyball players, it doesn't feel unrealistic that they could've retained their status as a consistent upper midtable club and pushed on from there.
Instead, in their rush to compete with us ASAP, they basically burned £100m on Sigurdsson, Bolasie, Tosun and Rooney to have their own 'Fab Four' like Liverpool, they went for the big name manager who didn't care a jot for them so they could play 'compare the manager' with Liverpool, they pressed ahead with building an unsuitable stadium so they could have a capacity like Liverpool, and have the whole time been hampered by the hair-trigger fuses of fans who seem to have been driven close to madness by the contrasting fortunes of the two clubs.
A remarkable act of self-sabotage, and difficult to believe it wouldn't have gone better if they hadn't had that mindset behind so many decisions.
