I still maintain he either resigned or threatened to, leaving us no choice. The relationship between RM & TB is very poor I believe and key players aren't too keen on him. The sequence of events as I understand it is that he went straight back to Italy after the Everton game, where he thought about things for a while then told Khaldoon of his intention to resign or at least was seriously threatening to walk if he didn't get backing.
He was ordered out to Abu Dhabi straight after the game and spent a couple of days there. I had assumed (and the informed sources certainly supported this) that he had said he was determined to resign at the end of the season but it could be that he was telling them that he was doing them a favour being here as he and his wife would rather be in Italy etc and would happily walk away if he wasn't backed.
So the club had to make a decision and they took the same one as when Hughes tried the same tactic so after Mancini came back TB went out there and they decided to approach Pellegrini. I'm also convinced he's a short term appointment to keep the seat warm for Guardiola in 2 years time and that's another story.
I said the other day he'd only committed to 3 years after signing a 5 year contract but afterwards I wasn't sure if he meant 3 years from when he started or 3 years from when he signed the new contract. However the latter makes more sense now. Guardiola was waiting to see what happened but having won the league, the owners felt committed to him and duty bound to offer him a new contract. He signed the contract but possibly to avoid unnecessary speculation they made it a 5 year one (or they've got a 3 year break clause). That left PG high and dry and he decided to take a year out to see what transpired but was told by us that there was a job there in 3 years time.
I'm also pretty certain the owners were worried about a media backlash if they fialed to offer a title winning manager a new contract, which they possibly wouldn't have done if he hadn't won the league. So it looks like Wigan's win against the rags and Aguero's goal against QPR have had all sorts of unintended consequences.
