Le Havre president Jean-Pierre Louvel says they've now contacted FIFA about Manchester United's deal for Paul Pogba.
Yesterday, a FIFA spokesman insisted no complaint had been submitted by Le Havre against United.
Louvel, however, told French radio France Info: "The player had a no-hire agreement, and so had to sign his first contract in France.
"But he didn't sign it because Manchester United contacted the parents and made astronomical and excessive financial propositions for a 15-year-old boy.
"We have submitted the case to Fifa. The letter to leave has not been agreed by the French Federation, so today Fifa has been referred.
"I hope we will get the same result (as the Gaël Kakuta case), which could justify to those clubs they can't do anything and they have rules to respect."
