The statement, in which he says his "relationship with certain executives and individuals at the club has broken down and is now beyond repair", was not the statement of a man bluffing his way to a new contract. Rather, his ever-changing rationale for his desire to leave smacks of a man desperate to get out of Manchester as quickly as possible. As every schoolboy who hasn't done his Physics homework knows, one excuse is better than many. So for Tévez to change his target from Roberto Mancini to Garry Cook and Brian Marwood does rather lessen the credibility of his critique.
Having seen this on Sunday, I presumed we'd seen the last of him at City. But he has attended training today, perhaps in the light of news that the club would take him and Kia Joorabchian to court should he go all Bob Crow on us. While I'm increasingly sure that he's going to leave, it does sound as if Real Madrid (by far his most plausible destination), will not pay for him in January. That being the case, we might well have a disgruntled Tévez, naturally stripped of the armband and back in the ranks, shuffling around until June. This wouldn't be an obviously bad outcome, he played some good football while in his final months at Old Trafford. It would also allow us to take more time over the selection and recruitment of his replacement. If the club don't want that (as would be very understandable) then he can be loaned back to Boca Juniors for a few months, as Robinho was this time last year.
So most of the possible outcomes are still in play, although I do think his staying here long term is a real long-shot now. Mancini will speak with him on Friday when the team return from Turin.
