I suppose if you look into it more deeply he's probably still pissed that Tevez left him in the lurch last season, and that had he been there, they could probably have won the title easier and earlier (though not as dramatically: how cool was that?) --- I think he should maybe draw a line under it.
Mancini: "Okay here's the lineup for Saturday. Carlos, you're in. Mario, get me a sandwich. And try not to mess the order up this time!"
Nah, he should realise he's handicapping one of his biggest talents and let Tevez have his first team place every week. They can't afford to be dancing around this issue, specially after yesterday.
