South Korean superkid Seung Woo Lee is being blocked from continuing his career with Barcelona.

The teenager is playing for Barca's cadet B team and has club coaching staff excited about his progress.

However, FIFA have ordered Barca to deregister 14 year-old Lee as he moved to Europe before turning 18, which breaks existing transfer laws.

Lee has been making great progress at Barca for over a year, but FIFA have acted after an anonymous complaint, says Sport.

Barca are now appealing the decision.
