Napoli boss Walter Mazzarri is planning to boost his attack with a Villarreal striker.
Nilmar and Giuseppe Rossi are both under consideration for Napoli.
Mazzarri said: "Yes I want him [Rossi] but with Lavezzi. I wouldn't have any problem leaving one of Rossi, Cavani, Lavezzi and Hamsik on the bench, not least because we'll be playing every three days.
"I want to manage top players whether it is Rossi, Tevez, Nilmar or Balotelli. I'd love to manage four top quality forwards."
