Napoli are struggling to reach an agreement with Dries Mertens over a new contract.
The Belgium striker is inside the final 18 months of his current deal and he's been linked with Manchester United.
There's reports of Mertens meeting with United intermediaries in Naples last week.
Meanwhile, Il Mattino says Mertens is demanding €3 million-a-year to stay with the Azzurri.
However, Napoli's last offer was €2.25 million-a-year.
