Napoli coach Walter Mazzarri says he won't block Eljif Elmas from leaving next month.
The midfielder is expected to be sold to RB Leipzig, with terms close to being struck.
RBL are offering 25m for Elmas, who is eager to see the deal done.
Mazzarri, after their Coppa Italia humbling by Frosinone, said: "I'm telling the truth, after the Scudetto if someone has the nerve to leave, I'm for making them go.
"Then the club will explain certain choices or not."
