Lorenzo Insigne has cast doubt over his Napoli future by conceding that an offer may come in future that he "can't refuse".

The Italy forward has spent his entire career with Napoli and, following the departure of Marek Hamsik, is now club captain.

But Insigne hinted at some unrest by revealing he could be tempted away from the Serie A outfit.

"I am 28 years old [this year] and it could happen that I receive an offer I can't refuse," he told Corriere dello Sport .

"I've proved what I am worth and there are people around who appreciate me."

Insigne's nine league goals have helped Napoli to second in the table, but Juventus is on the brink of securing the title.

Carlo Ancelotti's side is still in the hunt for the Europa League crown, though, and faces Arsenal in the quarterfinals.
