Le Havre defender Benjamin Mendy is eager to make the move to Marseille according to Jean-Pierre Louvel.
The 18-year old, who is reportedly close to joining Sunderland, is determined to force a move to Marseille but the Le Havre president says there has been no official bid from Les Phoceens which suggests a move to the Stade Velodrome may be difficult to complete.
"It does not shock me that he goes to visit Marseille. That sounds very normal for him to make his choice," Louvier told L'Equipe.
"But he knows that, to seal a deal with a club, you have to have the green light from Le Havre. And I repeat that we do not negotiate below what Sunderland have offered."
He added: "We have an agreement with Sunderland, but not with Marseille. There are no offers at the moment. Nothing has materialised.
"Marseille's offer should not be lower than that of Sunderland's.
"Everything will depend on Marseille's proposal. I have nothing against OM and I have a very good relationship with (president) Vincent Labrune.
"About the price, I have a confidentiality agreement with the English club, so I cannot tell you anything. But what is certain is that Marseille's offer should not be below that of Sunderland."
