Manchester United have been cleared by Fifa to sign 16-year-old Paul Pogba.French club Le Havre had claimed that they had agreed a contract with the midfielder for the current season before he went to United.But a judge appointed by Fifa ruled that, because of his age, Le Havre could not have got an agreement for Pogba to sign a professional contract.Chelsea were handed a transfer ban in September for inducing Gael Kakuta to break his contract with Lens in 2007."Manchester United are pleased to confirm that the Football Association has been authorised by Fifa to register Paul Pogba as a Manchester United player with immediate effect," said a statement released by the club.The ruling means United have not broken any Fifa rules - particularly the one dealing with the protection of minors. Fifa has advised the Football Association to register Pogba as a United player immediately.Le Havre are able to appeal against the decision.The judge decided Pogba was still an amateur because he only received normal expenses for playing for his club.Last month United threatened to take legal action against the French club unless they stopped making allegations about the deal.Source: BBC
