Napoli sports chief Riccardo Bigon says they're trawling the transfer market ahead of January's transfer window.

Bigon admits they hope to do business next month.

"The January window is always a difficult one," he said. "Perhaps we could send a few players who haven't played too much to other clubs.

"However, big name players don't usually switch clubs in the winter.

"We already have a good squad. We'll just have to wait and see if an opportunity to sign someone arises."
