Manchester United have threatened to take legal action against Le Havre over allegations that they offered financial inducements to persuade teenager Paul Pogba to leave the French club.
Following Chelsea's transfer ban for persuading Gael Kakuta to quit Lens, Le Havre officials have suggested that United broke the rules to seal the capture Pogba.
However, a strongly-worded statement from United read: "In response to the wholly unfounded comments widely reported in the media of Le Havre AC president Jean-Pierre Louvel, Manchester United wishes to categorically confirm that as a matter of club policy, and in accordance with the applicable football regulations, it does not offer inducements to the parents of players that sign for the club, such as monetary payments or the purchase of houses.
"Manchester United has written to Le Havre AC to put it on notice that action will be taken if such allegations are repeated in relation to the transfer of Paul Pogba.
"Manchester United is entirely satisfied that the transfer of Paul Pogba has been conducted in accordance with the regulations set down by the world governing body, FIFA.
"Manchester United is ready to defend any claim brought against it by Le Havre at FIFA.
"It is to be noted that all contractual documentation relating to the player's registration with the club has already been fully ratified by The Football Association and the Premier League."
