Napoli president Aurelio De Laurentiis has accused his Olympique Lyonnais counterpart Jean-Michel Aulas of going back on a promise to sell him Maxime Gonalons for €17 million.
The France international appeared set to move to the San Paolo this week, with the player having admitted that he was hopeful that the two clubs could come to an agreement over a transfer.
However, Lyon rejected Napoli's bid for the player, much to the disgust of De Laurentiis, who believed he had met the asking price.
"We made an offer to Lyon that corresponded with precisely how much they requested," the Partenopei supremo told l'Equipe.
"Aulas sent me a message some time ago which he said he would sell Gonalons and indicated to me the required price to be able to have him."
