I was addressing the guy that said we should play 4-3-3 with Dybala on the left and Cuadrado on the right. I even said 4-4-2 would be better precisely because we would have 2 strikers up front in their positions for attacking power not just the wingers.
Having said that, 4-4-2 is still not strong enough. You are acting like you know Pjaca's quality when we we dont even know if he can be as good as Cuadrado. But even assuming he is as good, our wingers would still be of a level lower than any other spot in our starting 11. I dont see any of our competitors having players of Cuadrado level playing in an essential role like wingers. Koman would be that player at Bayern if Robben is gone.
We have world class quality everywhere else in the squad. We are one CM away from having a complete 4-3-1-2, either by buying a CAM or a CM. 4-3-1-2 was effective, is a minor transition from the way we are used to play and the players available on the market make it much easier to complete than 4-4-2 and 4-4-3. We have witsel on his way as a CM, there are players like Isco, James, Oscar, Payet, Draxler (his agent said he wants us again btw), all who seem transferable and would slot in the 4-3-1-2 easily. That is not to mention that our bench for it would be set as well.
We don't have WC wingers for the starting 11 and even if those 2 are somehow good enough, we dont have a bench either. You'd have to resort to playing Alves and Sandro as your wingers.
IMO 4-3-1-2 makes most sense when Chisio is back, (especially if Witsel comes) as our main formation. 3-5-2 and 4-4-2 as back up formations for tactical shifts, this way we dont need to spend heavily on wingers that arent on the market. Ideally, Witsel in the winter, and Draxler in the summer.
Alves - Bonnucci - Chiellini - Sandro
Khedira - Marchisio - Witsel
Pjanic
Dybala - Higuain
And when Draxler is bought, deploy him as CAM, push witsel or Khedira to the bench. and let Pjanic take their spot. That way even if we do want to play 4-4-2 or 4-3-3, you can throw Draxler on one side and Cuadrado on the other without playing fullbacks as wingers or relying on some unproven kid.

Again what wingers do you have in mind that we should have bought or can still buy now? I can only think of Payet, Mahrez and Carrasco that can be seriously good and arent in very rich clubs. Even Bayern had to pay out of the ass for a completely unproven Koman and kinda lucked out with Costa.
