Serie A clubs are stepping up their interest in Liverpool striker Divock Origi.

TMW says Napoli and Atalanta are in contact with Origi's agents as they seek to bring the Belgian to Italy this summer.

Origi is seeking &uro;4.5m-a-year to move - demands which fall within the budgets of both clubs.

Atalanta see Origi as a replacement for Duvan Zapata, who is a target for Inter Milan and Newcastle.

Napoli, meanwhile, may move for the centre-forward as veteran Dries Mertens' contract runs down.
