Lazio defender Modibo Diakite is a Bosman target for Napoli.
His agent has confirmed that the Frenchman is keen on a move to Sicily.
"Napoli are the first option for Diakite," his agent Ulisse Savini told Radio CDC.
"To sign we are ready to make a financial sacrifice. He has undergone a medical in France because he suffered a bad injury four years ago, and that check with the doctor who did the surgery was planned. But he didn't have medicals with Napoli yet.
"We are not far from an agreement with Napoli. In the player's mind Napoli is the first choice. With what we lived at Lazio we can write a book. After Easter, I think we will define the situation with Napoli."
