The FA held an inquiry following allegations by Arsenal over Wicks, son of the former Chelsea centre-back Steve, but United escaped with being ordered to pay the costs of two hearings after they were found guilty of breaching FA Premier League rule F20.7.
The rule states that "no club shall directly or indirectly approach any boy who is registered as an associated schoolboy with another club with a view to inducing the boy to register with such first mentioned club ..."
Wicks was registered with Arsenal, who complained to the FA when the central defender later signed for the Old Trafford club.
Wicks, meanwhile, is said to be unhappy with life in the north and is keen to return to a London-based club.
