i literally just played that first formation now the 4-2-3n-1. I won 1-0 using 4-3n-2w-1. I dominated attack throughout the match.
orders: attacking/normal, down both flanks, mixed, zonal, own half, hard tackling (normal if he is under 5 qualities lower than you), counter on if using normal/counter off if using attacking, no offside trap. red arrows on AML/R and ST.

good luck
