Place your starting six players in their preferred position to avoid getting a stat penalty in Quick Games and minimize energy loss in Season mode. However at times it may be better in Quick Games to use your rarest or best players in any position if they will remain strong in that lineup. The goalie is a very important position, as he may get paired with other players. Level your goalie cards first. If you have a poor goalkeeper, intentionally lose the challenge by teaming him up with your worst card. This will increase your chances of winning the other match-ups and eventually the game.
