The main hurdle to overcome, no matter what the player wants, will be to convince Napoli. They have already set a 50-million-euro price tag on the player.
It's been months since rumours have appeared regarding potential suitors for Koulibaly, which is logical taking into account the harsh negotiator that is Aurelio de Laurentiis. The Napoli president has publicly expressed that he will not let a player of such quality leave his club so easily.
But PSG aren't giving up hope. The reason for the call was to know of Koulibaly's willingness to join the squad led by Mauricio Pochettino, where he would form part of a formidable back line alongside Sergio Ramos.
Whatever the player's wishes, however, it will be difficult to convince his employers, who have already placed a 50-million-euro price tag on their player.
