Napoli president Aurelio de Laurentiis has hinted they could sell stars this summer.
De Laurentiis, however, insists the champions are not reliant on a single player.
He told the Financial Times: "So many senators sold in the summer?
"Their desire to win was exhausted. I no longer believed it. Maybe I was wrong. But I'm the owner. I decide.
"The current squad won because they are a group, and not a single star."
