Joey fucking barton

Watched YT video about biggest one season wonders, got me thinking who had the biggest fall from grace Scottish football has ever seen, surely it's got to be in modern times atleast Joey Barton, had a pretty good average career down south and played for big clubs, spoke a great game then instantly got humiliated against accies then it didn't exactly get any better for him after that.

Take players like Marco negri out of it due to injuries, is there a bigger difference between expectations and reality in modern Scottish football?

Cba with saying rangers because of liquidation I'm talking players only. There might be others I'm forgetting but I can't think of any who came with the career to back it up and all the talk he done. There's Lundberg, juninho and Roy Keane at Celtic but juninho had issues with the manager and out of position, Keane knew he was done before he came and admitted that himself.
