French club Le Havre have said they will ask FIFA to investigate, claiming the teenager had agreed to join them, raising fears United could suffer the same punishment as Chelsea who have been banned from signing any new players until January 2011 for inducing Gael Kakuta to break his contract.
Football's world governing body on Friday said they have yet to receive a complaint, a spokesman said: "There has been no receipt of any complaint by Le Havre regarding this player as of today."
United would launch a vigorous defence of their position if the case was referred to FIFA as they insist they have done nothing wrong.
A club spokesman said: "It is complete nonsense. Everything has been done within UEFA guidelines."
However, Le Havre managing director Alain Belsoeur claims to have documentation showing United offered inducements for Pogba to join them and has vowed to include it in submissions to FIFA.
"We are still pursuing our case," said Belsoeur.
"It is a very serious case. We are confident that we'll win because it is in the best interests not just of our club but of sport."
