Here are the different steps you need to do to earn those unique rewards in Squad Building Challenges:
Check the Requirements
When starting to build a Squad in FIFA 23 SBC, you will see a list of requirements on the right side of the screen. These are the requirements you need to meet to earn the rewards.
Create a Squad
The pool of players you will choose from will be cards in your club. If needed, you can also go to the Transfer Market. It is recommended to use unwanted cards in SBCs. Double-check your squad to see if all the requirements are met. Substitutes, reserves, and managers are not taken into account.
Submit your Squad and Earn Rewards
When you are sure all requirements have been met, you can submit your squad and earn special rewards.
