4-2-3-1 would be great imo.
We could play Licht-Barza-Bonu-Chiello back 4 which could then change into a back 3 in offense with licht moving further up to make a 3-3-3-1
In the MF I would play Pogba-Asamoah. Both are very physical but also good passers, spreading what would be Pirlo's duty between the two. Also makes it harder for us to be shut out like when Pirlo is.
RAM we would need someone with great crosses. A natural winger would probably work better than a foward like Vucinic. CAM I would play Vidal, he has a great ability for defence splitting balls but also would give us much higher intensity allowing us to win many balls higher up the pitch. He is quite decent on the dribble and faking out opponents, so he could probably create many chances for himself. LAM I would play Vucinic in the same as role as when he played left in 4-3-3 last season. Asamoah could also be used to make runs from deep ala Marchisio with Vidal dropping a little deeper to cover. Marchisio would make an amazing sub or rotation choice, he could easily start too. Pirlo could be used in lower intensity games, like most Serie A matches.
