Napoli director of sport Riccardo Bigon admits they'll be active in the January market.
Wolfsburg winger Ivan Perisic and Liverpool's Lucas Leiva have been linked with Napoli this week.
Bigon said: "Some of the rumoured names are correct, but there are others we are tracking who haven't emerged in the papers yet.
"Obviously sometimes transfer strategy is talked about just to make news, but we accept that, as it's part of the game."
