I would keep your current formation but instead of a AMC i would go for a DMC with blue arrow! I would put on all your MC's and Strikers a Red Arrow! I would play attacking, zonal, mixes passing, offside, own half, hard tackling! I'm playing this formation 2 seasons now and have won all my games when i faced that formation! My friend play that formation and he lost all his games against me, but won all his games against other players in the League
Take a look at my team showcase for that formation! If you want extra information take a look here ==>
