but in all honesty its about balance and compromises
See, when players add so little in the defensive department, in giovinco's case a negative number, they need to make up for it.
Messi,Hazard, Gotze, .... all add absolutely nothing defensively. But their endproduct is so damn good, that the coach just compensates by limiting other players so they can play at their best.
In a 433 we got a midfield of 3 of Pogba, Marchisio, Vidal, Pirlo. Players who are significantly better then Giovinco. Why would they have to be limited offensively to balance out giovinco's total lack in the defensive department ?
Every single moderately succesfull 433 had wingers to fear. its THE feature of the team. Seriously, Giovinco LW ? PAUL POGBA beeing limited to compensate for Giovinco, are you fucking kidding me ????
Thats why he never plays. He offers far to little.
