I think a 442/3142 fixes some of our issues in attack:
Defensive Block
------------------Ferran--------------Jesus
Foden/Silva---------Gund-----KdB----------Sterling
Cancelo-----------Laporte----Dias-------Walker
Attacking Phase
--------------------Ferran----------------Jesus
Cancelo-------Foden/Silva---------KdB----------Sterling
--------------------------Gundogan
--------------------Laporte----Dias-------Walker
My Thinking for it (purely on maximizing player potential)
1. Ferran plays better as a inbetween winger/striker, his dribbling, finishing and link up play are better than Sterling's, and combined with Jesus (who has the same assets), makes them a great pair up front to finish chances.
2. Chemistry between Ferran, Cancelo, Foden/Silva I think would be really good, Cancelo-Silva read each other well, and Foden-Ferran read each other well.
The idea would be to build up play on the left side, and utilize Sterling's speed and positioning on the right.
3. Somewhat fixes the Foden and KdB problem by making Foden play as a pseudo winger/midfielder, KdB can still operate a bit deeper and try his risky passes.
4. Player depth:
Mendy LWB
Ake, Stones CB
Rodri DM
Mahrez as Sterling back up, but also potentially up front as a creative striker (could redefine him)
Silva LM or RCM
