To get the manager bonus

To get the manager bonus, players should try to match the manager nationality or the manager league with the higher number of  Fifa 16 Coins players from the start eleven. Pay attention that it may not be always true.

For example: if all the players except one are from one specific league and already have individual chemistry 10, it may be better to try to match the manager league with the league of the only player that doesn't have the higher chemistry possible.

When a manager league's doesn't match with the player's league, it's possible to fix this applying a league modifier card.EA recommends trying the code a second time to make sure you typed it correctly. If that doesn't work. turn your console off completely, not just in rest mode, Buy Fifa 16 Coins and then try it again after a full reboot.
