Allegri still needs to settle on a formation & stop tinkering so much especially with the back four. Moved on to a 4-3-3 now with Boateng as a false 9 last game, i wish he'd just stick with the 4-2-3-1 because starting Nocerino is pointless right about now. (although credit to him for working his socks of vs Juve) but still it's dificult for Allegri with far too many changes at the start which should have been a more gradual process, not just throw out an entire XI with a completely new team and making it work.
I think the performances recently & at times earlier have been encouraging, but there has been some howlers. The games vs Malaga & Fiorentina spring to mind, where not only did we lose, we played poorly.
We'd have beaten Napoli quite comfortable if it wasn't for Abbiati being a helmet.
