against 4-1-2-1-2 i always use 3-1-4-2 both flanks, red arrows on ML,MR . this formation never dissapointed me against the diamond
Finaly i will try ur advice i have a cup match in 50 min away (1st 0-0) , and a champions match in 2 hours , playing the same formation . I will play as u said 3-1-4-2 ( with no AMC players) and i will let u know the score
