Napoli president Aurelio de Laurentiis is upset with star striker Edinson Cavani. Tuttosport says Cavani's agent Mino Raiola is demanding new contract talks with De Laurentiis - which has angered the movie mogul.
Raiola is now seeking a new deal for Cavani worth 3 million-a-season until 2015.
Tottenham are monitoring developments, along with Chelsea and Manchester City.
Raiola placed Mario Balotelli at City last summer.
