Parma president Tommaso Ghirardi has revealed the interest of Napoli in Marco Parolo.

Ghirardi admits he could sell Parolo.

"Napoli have been to watch Parolo," he told Radio Kiss Kiss. "But so have other clubs.

"Price? I'd settle for half of what was paid for Radja Nainggolan. I think Parolo is the number one target for a lot of teams this month."
