Napoli president Aurelio De Laurentiis admits they must sell before buying again.
ADL has revealed they're keen on Fenerbahce youngster Eljif Elmas.
He said, "We are receiving many requests for Mark Rog, both in Italy and abroad.
"He has a lot of quality, even if he hasn't played enough. We are waiting, and if he leaves, then Eljif Elmas is a profile that would suit out team.
There are a lot of offers for Adam Ounas too, but we're considering the situation, because he could be of real use to us, too."
