Though the online elements of FIFA become more popular with each passing year, career mode is still played by millions. Whether it be in pursuit of stabilising a struggling club, pursuing world-domination or simply taking over your childhood team, career mode allows FIFA players worldwide to prove their credentials in terms of gameplay, man management and recruitment. Now, if you're starting as an oil-rich team like Manchester City, you probably aren't too interested in building for the future. If you can afford players at the peak of their powers, why buy someone that will develop to the same level? If you're actually challenging yourself, however, you'll need to use your budget wisely. This is where wonderkids come in to play. By definition, this article views a wonderkid as a player aged 21 or under, with 85 or more potential. The advantage of these players is they tend to be cheaper than world-beaters, and they reach the same, if not higher, level if given plenty of game time. Here's a starting XI of the best wonderkids available in FIFA 16 career mode. Grab ahold of these lot, and it would probably be harder not to win the European Cup after a few years have passed. If two players in the same position have the same potential, please note that the player with the highest current overall has been selected.
