I agree that a standard 442 looks like the best way to go. It looks like you have three players that can play AMC - Dan Webb, Ben Drake, and Nicao. That said, with nobody listed as a DMC I would just go with a plain 442 for now. You can always set your most creative player as an attacking midfielder from one of the central mid positions and achieve a similar style of attack as if you had an outright AMC. The same can be done with your most defensive-minded center mid set as a deep lying playmaker. I did this with my current Man City team but went with a wide diamond 442 after getting my roster shaped the way I wanted.
