Napoli president Aurelio de Laurentiis says they're prepared to sell Arek Milik.
But he insists the Pole will only leave for their assessment.
“Milik has always been on the market," De Laurentiis told Sky Sport Italia.
“Since I've known the man, I've been asking him to extend his contract. He just looks at me and doesn't reply. So at that point, you have to accept he has to leave."
“Milik will go to the highest bidder, because there will be no discounts for anyone. Otherwise, he risks staying at Napoli and will probably no longer be picked by the coach."
