plus there's the midfield. pirlo said at the beginning of the season that all of our midfielders were better suited to a 2-man midfield, yet i don't see anyone being comfortable in this new midfield, maybe save for rabiot. for me, especially with dybala's current form, 4-3-3 is the way to go. no slow transition, more defensive solidity, most players (including cr, morata and the mids) are familiar with the respective roles.
pirlo seems to stick with his idea though
