My thought is to always have balance on the pitch, unless you're particularly strong down one side of the pitch. You could have your wider AM's on support roles if you want your FB's to get forward and then the AM's to feed them. It depends where you want your FB's in the attack and not just where you want your AM's. You've got shorter passing instructed and so you need to think if you're giving your CD's enough options to pass out if your FB's are going to be bombing up the wings. Yout 2 CM players should drop back to offer a pass but will the be marked? It's thinking about the picture leading up to the attack and not just thinking how you'll get goals once there. Nothing you're doing is wrong really but it's just thinking about how you want to play. Your FB's will give you width but they'll be making a move up the pitch as you're trying to build from the back and so more often than not, they'll just punt it anywhere. AP's will usually drift out wider and SS's will drift out wider but will want to be a threat in the box too My personal choice would be SS on both wider positions, treq/enganche in middle and FB's on support with get forward more ticked. That would be my choice as a starting point and then seeing how you feel that works. Just think that if you have more players darting forward then you need others to pull back to give an option for a pass
