Napoli president Aurelio De Laurentiis has admitted that he wouldn't stand in the way of star defender Faouzi Ghoulam if he decided to leave.
Ghoulam, along with Dries Mertens, are two of Napoli's best players and are also two of the most sought-out stars in Europe.
There is a €30m release clause in Mertens' current contract, but Ghoulam's deal expires at the end of the season and the Italian side have so far failed to agree an extension.
It is believed that a satisfactory release clause figure - for both parties - is the cause of the stalling in negotiations.
