Napoli are testing the ground for Benfica midfielder Nemanja Matic ahead of the January market.
It's emerged that Napoli representatives have made contact with Benfica this week about Matic's availability and a price for the winter transfer window.
The former Chelsea midfielder's contract carries a €50 million buyout clause, but Napoli president Aurelio de Laurentiis has been told Benfica will sell for €30 million.
The Serb has also been linked with a return to Chelsea this season.
