The Uruguay international has angered the Partenopei by asking for a pay rise - just 12 months after signing a new five-year deal with the club
With the Partenopei supremo seemingly powerless to prevent Ezequiel Lavezzi from leaving the San Paolo this summer, the film producer is reluctant to allow Cavani follow his fellow South American out the door.
However, Marotta is still doing his utmost to convince De Laurentiis to sell the Uruguay international, according to Tuttosport.
The Bianconeri's cause has reportedly been aided by Cavani's demand for a new and improved contract just over 12 months after putting pen to paper on a lucrative five-year extension, a move that is said to have infuriated De Laurentiis.
Tuttosport also claims that Arsenal forward Robin van Persie remains Marotta's primary transfer target but that Juve accept that they could well be outbid by Manchester City.
In such circumstances, they would then consider making an approach for Edin Dzeko, who would most likely be deemed surplus to requirements should Van Persie arrive at Eastlands.
