You bring up an interesting comparison, which perhaps highlights our problem.
Both Liverpool and Man City morph into a 2-3-5 in attack. Essentially, they always want wide players hugging the touchline, two players in the half-spaces, and a forward (creating the 5).
Whereas Liverpool create this with wide FBs and inside forwards (Liverpool have quite a rigid midfield three), Man City have touchline-hugging wingers and free 8s in the half-space (Man City's FBs are inverted and play quite deep, creating the '3' with the #6).
We're caught in the middle: Wingers hugging the touchline, getting in the FBs way, and no free 8s. It's like Man City's wingers and Liverpool's rigid midfield-three. It doesn't create the ideal 2-3-5 line-up.
We need to keep the rigid midfield-three and get our wingers playing in the half-spaces, and high FBs; or keep the wingers wide and get some free 8s (which we technically have, in Tillman, Hagi, Lawrence, Jack at a push) to support the forward more closely.
