FIFA Manager 12 features improvements to virtually all areas of the game, including major enhancements to the 3D mode, finances, transfers and the calendar. Changes to the 3D mode create a more realistic experience, and include new logic, new player artificial intelligence, and marked improvements to tactics, substitutions and the conduct of opposing managers. In addition, a new intuitive user interface makes it possible for players to retrieve all the data relevant to the game within seconds and to issue precise tactical instructions to their teams.

Managers can also commission a detailed analysis of the squad so the team's weak points can be specifically eliminated.
