even barca doesn't have wc wingers, so the point is moot, unless you believe juve can't even afford some good enough wingers.
You dont understand the point of live.
Barcelona is a team with gigantic creativity. Their attack originates from the center of the field combining, wilst the wings are mainly used to stretch the play, but not really creating danger. They want fast, players there, and thats it. Pedro, Iniesta(waste to play him there tho) and sanchez are excellent for that.
Why would they need wings ? to cross it to messi.
Nope, they stretch the play, creating channels for the cm's to move in, attempting trough balls to the forward(s)
Their creatvity is abundand, and their defence basically is the pressing game.
Juventus on the other hand, has much less creativity. The creativity it has, need to be of high class. Vidal, Marchisio, Pogba, our flanks, thats not really creativity. They can make personal actions, but not really create openings.
Tevez and Pirlo however, can. They draw players onto them, and attempt to crack a defence, allowing space for others or assisting/key passing in that space for a goal.
If we take away pirlo, our team is nearly deprived of its creativity. Basically there is tevez, and pogba lobbed passes. That is not enough.
IF you add wingers and remove pirlo, the wingers need to compensate for pirlo. That requires world class wingers quite simply, as the entire team compensates for them beeing there. It would mean tevez doesnt play, and pirlo+vidal are forced to stay deeper holding the midfield
4-3-1-2 allows vidal and pogba to press aggressively and make forward runs, pressuring the holding midfielders and central defence, whilst a central attacking playmaker and tevez create.
Because marchisio's better holding skills, pogba and vidal can attack far more frequently and fanatically. Because of the tevez+cam in front, pogba could swerve to the side where is space and send high balls to llorente
Good luck comming with a better formation then a 4-3-1-2 with Mata
