Had already voted for Allegri. Now, if Moggi (say what you will about his character, he's exceptionally astute in footballing matters) agrees, then I'm even more for it.
At this point, with this current incarnation of Lippi, I couldn't care less for his recommendations.
Allegri has Cagliari playing some good football, with, if we're honest (and I'm Sardinian myself), a pretty lackluster squad. I think it'd be interesting to see what he could do with more quality at his disposal, although these days, we're hardly quality ourselves. Regardless, he's gotten them to overachieve, definitely.
Prandelli, I don't know. He's just always struck me as inconsistent. How much this is down to his players, I don't know. He also seems rather timid.
