Marseille chairman Pape Diouf has hit out at his Lyon counterpart Jean Michel Aulas for unsettling Franck Ribery.
Ribery is hoping to win a move to Lyon after becoming unsettled at Stade Velodrome.
Aulas claims Ribery has agreed to move to Lyon and that they are waiting for the green light from Marseille to seal the transfer.
Diouf is unhappy with the behaviour of Aulas and has accused the Lyon chief of tapping the player up while visiting the French national team in Germany.
"We have to ask ourselves the question of the exploitation of the boy (Ribery), when you know a club's official can live close to him in the French team sanctuary," said Diouf.
"The rules absolutely forbid chairmen to talk with players under contract."
