Napoli chief Riccardo Bigon admits they're planning for the January market.
Bigon says he'll be looking to reinforce the side further after Christmas.
"We will do what we deem appropriate," he told the Corriere dello Sport.
"We demonstrated that with the [recent Bosman free] purchase of Anthony Reveillere. There was an emergency and we filled it immediately.
"We'll see if we will need anything else and look around to see if there are players with the technical profile Napoli look for.
"As President Aurelio De Laurentiis says, we are always looking at the evolution of the transfer market.
"We will always be competitive, even more so. The fans want success and so do we!"
