Napoli are offering a £1m loan fee with a £26m option to buy for Tottenham midfielder Tanguy Ndombele.
The Italian club are confident of securing the player's signature while the Frenchman is said to have told team-mates that he is bound for Campania.
Negotiations accelerated after Napoli's opening weekend victory over Verona which settled some of the bubbling discontent in Naples this summer.
The club have lost Kalidou Koulibaly to Chelsea, Dries Mertens to Galatasaray and Lorenzo Insigne to Toronto FC.
The three players formed the backbone of the Napoli team for a significant number of years and fans had grown to be unhappy with the club's owner Aurelio De Laurentiis.
