Napoli are interested in Inter Milan midfielder Fredy Guarin.
Corriere dello Sport says Napoli are prepared to part with Dries Mertens if Inter include Guarin in their offer.
The Nerazzurri are interested in the Belgium international.
Inter failed with a previous bid of €6 million plus Andrea Ranocchia for Mertens earlier this summer.
But an offer including Guarin could convince Napoli to sell.
