Although I sort of agree that our strongest line-up is 442, the big question for this one is Khedira, Matuidi, Marchisio, Sturaro and Bentancur - I don't see them playing anywhere apart from the middle two and having 7 or 6 CMs is a waste of resources if you're playing only 2 of them in your starting 11. Surely Allegri will try out a bunch of 3 CMs stuff first and stick to a 2 CM formation only if nothing else works, like in 16/17.
