Do you really think he would have hung around while we were still in the Championship and he had other offers dangling in front of his eyes? Regardless of what we offered him to stay? This is a man who once made flattering eyes at Leeds bloody United, when they were lower placed in the league than us. His relationship with the club was already fractious long before the play offs, hence his pre-Palace (the 3-0 home win) tantrum.
I don't think he'd have stayed even if we paid him two million quid a year.
I completely agree, Gus has a huge ego and wanted to manage in the Premiership with or without us to take him one step closer to his Chelsea 'dream' is my take on it. (You can't really blame him for wanting to manage at a higher level but what I'm saying is I think he'd had just about enough and wouldn't have stayed even if we offered him the highest budget in the league)
