I'd go for a 4-3-1-2 not a 3-5-2.
3-5-2 without a playmaker or even someone can hold possession at all is going to be a recipe for disaster. You can't expect pereyra and staruro to distribute. We'll lose possession and get countered regularly while we will be unable to create upfront.
This reminds of Milan 2011. Nocerino, ambrosini, Kevin Prince Beotang and Van bommel in midfield while Ibra is tasked with everything else.
Manzukic and Dybala in Attack.
Pereyra behind them
Pogba, Padoin and Staruro
Call some CM youngsters to the bench in case of injury. Shift to 4-3-3 if an injury happens and the game is not won yet.
