Suso plays best in the 4-3-3. It's his ideal formation. Unlike Hakan, he's not a midfielder. A 4-3-3 doesn't necessarily require two goal-scoring wingers. Rather, having a goal-scoring winger and a dribbler/assistman is more balanced and would work much better.
But if you wanna play Suso, a left winger, and two forwards, we're basically playing 4-2-4. Not only it's unbalanced, but where would Paqueta fit?
With the big hope of signing Fabregas, my wish would be to sign a LFW in January, and play like this:
Donnarumma
Conti - Musacchio - Romagnoli - Rodriguez
Kessie - Fabregas - Paqueta
Suso - Higuain - LFW
Btw, apparently we had reached an agreement with Sevilla for Muriel on loan, but he chose Fiorentina over us. And I'm kinda glad. I don't think Muriel is the solution for us right now. We need someone good.
