Napoli director of sport Riccardo Bigon admits they will be seeking to strengthen almost every area of the squad.
Napoli have been linked with the likes of Luca Toni and speculation that they would make a bid for the Bayern Munich striker reached fever pitch late last week.
Speaking to Marte Sport Live, Bigon said: "The attack will be the only area in which we won't intervene, because it's where we have numbers and quality."
