Here is the new list of the best young players for FIFA 12. It should be accurate for current-gen machines (PC, XBOX360 and PS3) and at least a good guide for those on previous-gen machines.
Players ages are calculated at the start of a manager mode season with a Premier League club (1 July 2011), and for a player to be included on this list they must be under 25 and have a potential overall of 75+.
Many of you have players whose overall has exceeded their potential. This is because a player should naturally reach his potential, but by playing them often you can boost their overall potential. In the past this boost has been anywhere from 1 to 10, but more likely 3 or 4. This is an overly simplistic view of things but it tends to hold true in most cases.
