Saying Roman will sack because he done it before is just to easy a way to look at things, I eat a tub of Harbenero sauce a few years ago and I sure as hell ain't doing that again. I'm not saying you're wholly wrong, but you altered the context of this story of sacked managers ever so slightly. While your reasons in hindsight might be true regarding all these managerial sacking let's not cover this in blue-tinted glasses. Roman & the board are ready to pull the trigger on any manager they feel won't be able to dig themselves out of a rout the club would go through. While they can be briliant, like in this transfer window, they have the ability (and demonstrated the ability) to undo it all with sacking a manager. Mourinho won't be a special exception imo. If there isn't silverwear this season, the unfortunately I think the OP was right with the post you replied to, he will be sacked. Mourinho might be special, but in the board's eyes there's Guardiola, Conte and whoever else is going to flavour of the month by the end of the season.
