I believe that players like Pereyra, Giovinco, Tevez, Coman can be used in another system than 3-5-2. Giovinco certainly should never play as a striker, Pereyra is versatile and can occupy multiple positions, while Tevez can be deployed on the wings. Coman and Morata as well fit into category of players that can be used on various positions, but it requires that a coach is inclined towards a change, something that Conte rarely was and when Italy's spot was left vacant he quickly seized the opportunity. It was never about not meeting his demands as this mgmt provided him with abundance of talent during the years.
