Ultimate Team features 100 icon players, including 11 new names. Eric Cantona, Petr Čech, Ashley Cole, Samuel Eto'o, Philipp Lahm, Ferenc Puskás, Bastian Schweinsteiger, Davor Šuker, Fernando Torres, Nemanja Vidić, and Xavi all feature as icons for the first time. Jens Lehmann will not be an icon in FUT 21.
Ultimate Team will see the addition of a co-op gameplay feature in the form of Division Rivals, Squad Battles and Friendlies with a friend online to unlock objectives and rewards. FUT was surrounded by controversy due to it being classified as a "loot box" and a source of online gambling. FIFA points were already banned in Belgium and could be banned worldwide soon. The players can customise their own FUT stadium with tifos, pyrotechnics, trophies, music, statues and stands as their FUT club grows. In-game stats can now be upgraded individually for special cards (the example given is if Trent Alexander-Arnold scored a free-kick for a TOTW in-form item, the free-kick accuracy can be much higher than his other in-form items). Live FUT friendlies combines house rules with squad rules to create different match types that change throughout the year. Redesigned menus allow the access to their squad and stadium directly from anywhere in the main menu. In new FUT events, the players can pick sides and compete against the FUT community to unlock packs, coins, club items or players in Team Event Objectives. The players can work together with the entire community and earn shared rewards by completing objectives as a collective.
The Top 100 will be expanded to Top 200 in FUT Champions. 30 matches in Division Rivals contribute to their weekly rating. They can play more matches for skill points and FUT Champions points but they won't increase own rank. Players can make extra coin rewards when they get promoted to a new division for the first time in Division Rivals. Squad Battles can be used to determine their rivals division at the start of FUT 21.
Fitness and training consumable items have been removed from the game. Players will still lose fitness and stamina during a match, but will automatically start their next game at full fitness. Healing items have been simplified to just gold common and rare items.
The player's club can be transferred from PlayStation 4 to PlayStation 5, and from Xbox One to Xbox Series X and Series S, but not from PlayStation to Xbox or vice versa though.
On 9 September 2020, EA Released the Ultimate Team ratings of the Top 100 Players. Barcelona forward Lionel Messi topped the list with a rating of 93, followed by Juventus forward Cristiano Ronaldo with a 92 rating, and Atletico Madrid goalkeeper Jan Oblak, Paris Saint-Germain forward Neymar, Manchester City midfielder Kevin De Bruyne, and Bayern Munich forward Robert Lewandowski all with 91's.
Career Mode will see new additions following years of criticism from the community - mainly to the manager mode. New additions include; a revamped interactive match simulation mode, which allows players to instantly jump in and out of matches in addition to changing game plans in real time. A new and improved training system which allows for weekly training schedules and the ability to train players to play in different positions, new stats such as match fitness and growth, an improved youth academy system, more transfer options such as loan to buy deals, and enhanced opposition AI.
