The France international wants out of St. James’ Park this summer after the club was relegated to the Championship last season.
The 26-year-old has already expressed a desire to play for Arsenal, but it appears as though his next destination will be Italy.
Napoli and Roma, according to Calciomercato, are keen on Sissoko and they are now putting together proposals.
Newcastle are aware of the Frenchman’s desire to leave – but they are not going to let him go on the cheap.
The Magpies will not set for anything less than £14m and it will be up to Napoli and Roma to offer that amount.
