When I choose a player like Dejan Stankovic, it shows with green and/or red where he can play. Like CM,SMF,AM. However when I bought the PES6 Guide, they sugested to play him as a wingback. Is this a typo, or can he play there? A pal told me that you get "hidden attribute drops" on the player if you play him in a position where he cant play. Right or wrong?
