Hey Rage,
Why attacking down both flanks if your attacking power lies in the center? You also have a DMC. That means that your axis is DMC -> MC -> AMC -> STR. So attacking through the middle makes more sense. Attacking down the flanks would require more like a AML and a AMR. I would really look for that and go for a 4-3-2-1 formation. AMR and AML right now score a lot more goals somehow then most other players. I have 2 teams and all my AML/AMR's are at something like 1 goal per game and 0,5 assists.
If you want to stick with your formation then use the red arrows on the MR/MC/ML/AMC and maybe even on the DMC.
