Napoli president Aurelio de Laurentiis admits they're interested in Lazio midfielder Cristian Ledesma.

The Argentine is expected to be sold by Lazio in January after rowing with management over his contract.

"I like Ledesma a lot, but at times signing a player who is already fully formed doesn't represent a good investment," said De Laurentiis.

"As for the rest, there is a list of names styled by Mazzarri and Riccardo Bigon."
