It is one thing to have players that may be startable on the wings and its another thing to have players made for playing on the wings.
you'll be shifting two centerbacks (one of which is world class) to fill a full back role. Asamoah (a make-shift WB already) would be utilized as a left winger when his defensive qualities are his best attributes. Isla would be completely without a position while he is already struggling to fulfill his natural WB role. You'd have bonucci's weaknesses exposed by removing him from his best position (has has demonstrated plenty of times that he works best in the middle of a three man defense). I dunno where Pirlo fits in this equation.
You'd have Tevez playing outside of his best position. You'd have mediocre players like giovinco as starters.
The players that wouldnt have to be played outside of their best position would be Licht, Barzagli, Vidal, Marchisio, Pogba, Giovinco (who'll have to be a starter) and Llorente (who'll start too). Chiello, Pirlo, Asamoah, Tevez, Vucinic would be underutilized.
In the 3-5-2 our best players are starting in their best positions. Second best players are substitutes that play out of their position like Giovinco and... i can't think of anyone else.
