The Composed Authority Evolution is a new feature in FC 26 that allows players to enhance their defenders significantly for a cost of 50,000 coins. This evolution consists of five upgrade levels, each offering substantial boosts in various attributes such as overall rating, ball control, and defensive skills. For instance, the first level provides a +10 increase in overall rating, while subsequent levels enhance attributes like acceleration, agility, and tackling. To achieve these upgrades, players must complete matches in Squad Battles or other game modes, meeting specific conditions for each level. Notable candidates for this evolution include Sol Campbell, Arrey-Mbi, and Maldini, who are recognized for their defensive prowess. With the right selection of players, gamers can maximize their Ultimate Team's performance through the Composed Authority Evolution.
