Former Napoli defender Ciro Ferrara isn't surprised hearing Luciano Spalletti could leave the club.
Spalletti has hinted he could depart Napoli after leading them to the Scudetto.
Ferrara said: "I'm not surprised by his farewell. It's normal that people who were thinking of celebrating were surprised. But it's part of the world of football, you have to respect the will of the parties.
"He will always be part of the history of Napoli, he will be remembered forever."
On the transfer market, he added: "There are no non-transferable players, not even among the strongest. In history there has only been one who unfortunately is no longer with us, that is Maradona."
