Napoli president Aurelio de Laurentiis says he will sell Bari if they earn promotion to Serie A.
No individual or company can own two clubs in the same division in Italy.
De Laurentiis commented: "I'm fighting to equalise the South to the North, it's no coincidence that I'm also the owner of Bari.
"What will happen if we arrive in Serie A with Bari? We'll sell them.
"But it will go to someone who will know how to handle the club properly."
