Well, at least we would be able to win the Coppa then, that is more then what we will win if Ranieri stays our coach.
But no, I don't want Mancini as our coach.
He also won it when Inter wasn't as strong yet as they are now (damn that feels bad to have to say that) but true, their team was stronger then what we have at the moment.
If he started all of his available quality players (especially when there was no reason to rest them for other immediate matches), chose a formation that suited the strengths of the players at his disposal, made effective substitutions (and used all of his subs when the situation warranted using them all), and didn't play scared football...
