These stuffs above were tips from top 11 forum for da new game engine. Briefly, no matter how ya set ur formation, keep your focus passsing mixed, if your squad is 1,2 stars above your opponents (normally only set arrows on 6 star players), get red arrrows on mcs, amcs if you attk through middle, to mr/l if ya attack through flanks. On the other hand, if ya squad is not too strong, just keep it as original without arrows, if ya have dmc, press ur rival in own half, if not press them at whole pitch. Hope these would be helpful.
