Could also say if Mancini/City had handled the situation better they would be champions. Either way, they self destructed in spectacular fashion.
Mancini handled it exactly how he should have imo. Tevez's fault when it all comes down to it.
Mancini has lost all credibility this season, twice, by jumping the gun and saying Tevez and Balotelli would never play for the club again only to look like an idiot afterwards. Mancini should take a page of Pardew's book when it comes to not putting extra focus on these sort of things (Ba refusing the hand shake for example); he reacts in typical Italian fashion, without thinking things through and I think City owners and fans will point to exactly this when they evaluate where they lost the title to their rivals.
Lost all credibility? Aye, right. Post-match interviews balanced against numerous trophies.
