Napoli are willing to sell Kalidou Koulibaly and Fabian Ruiz this summer but have yet to receive suitable offers.

Calciomercato reports that the Serie A side need to reduce their wage bill and raise funds after missing out on Champions League football for a second successive season.

Piotr Zielinski has also attracted interest from a number of Premier League sides, though Napoli would rather sell Koulibaly and Ruiz before the Poland midfielder.
