Red arrows don't make a player play in new position front or back of him! Arrows are individual mentality for each players apart from the team mentality. Example team mentality is normal, red arrow on AMC will make him having attacking mentality and be more offensive than the rest. If the team mentality is attacking then his mentality is ultra attacking. I don't think it's movement as according to some ppl suggested the arrows need more directions. The only thing I can't seem to fully understand is the arrows for the gk. any thoughts?
