Easy for people to say look at what they've managed with those sackings, but put another way.
They came down and had parachute payments, they then got players on the cheap from other clubs owned by the Pozzo family to get promoted again.
They've then had parachute payments each time they've come down again since.
Is it really a surprise they've been up and down so often?
In fact it's arguable that had they had some stability they could have got up and got themselves established like a Brighton.
