Swipe to the left from the "Formations" screen to set the player orders. Set the drop down options to your preference. The most important settings are at the lower right corner. You can assign players to captain, corner kicker, and penalty kicker if that player has a displayed unique skill. For example, if one of your players shows that he as special skill as corner kicker, place him in the top position of the corner-kick option screen. Besides ordering players based on special skills, place them as follows: LM as left corner kicker, RM as right corner kicker, strikers as the first two penalty kickers, and the player with the most stars as the team captain.
