Napoli president Aurelio de Laurentiis remains hopeful of keeping hold of Dries Mertens.

The striker is inside the final 18 months of his present deal and fielding major interest from England.

Sky Italia says ADL hopes to convince Mertens to stay with a bumper new offer.

He is willing to double his salary to €3.2 million and extend his deal by five years.

Mertens can earn more going to England, but ADL is counting on some loyalty from the player after pushing the boat out over a new deal.
