Each week in Squad Battles is an entirely different competition. Your rank is determined by battle points and you earn them by playing matches. The criteria for each rank is based off all the player’s results who are taking part in a Squad Battles event. Each Rank can only hold a certain percentage of the players competing during the current week. FIFA 21 Squad Battles rewards are delivered every Monday at midnight (UTC time). You don’t need to redeem your rewards in the week they are assigned to you. They can be stored to be opened later. They don’t expire.
