He's done immeasurable damage to his reputation and legacy
It could be repaired in time, but for the foreseeable he will be persona-non-grata at the club that made him famous
I don't know what made him think he could have ridden this one out. Sure, maybe he'd be out in the cold in the short term as part of Kenwright's revenge, but once new owners were in place he could have easily worked his way back in and would have retained the respect and appreciation of the fanbase
It's quite a tragic tale in all honesty
The damage was done, with his “ one man and his dog ” comment.
He was never coming back from that and showed his true colours.
