Jorginho spent four years in Naples before following manager Maurizio Sarri to Stamford Bridge in 2018.
The player has often been linked with a return to Serie A, and his agent Jorge Santos this week told Radio Marte: "If Napoli will make an offer, we'll evaluate it. He had a great time in Naples, and he has many friends over there."
Jorginho has done nothing to dispel reported interest in a return to the country, telling Canale21: "There are no words to describe how much I miss Naples.
"Who wouldn't miss Naples? It's so cold in London, they don't even know what the sun is."
Jorginho continues to be a regular for Chelsea, under both Frank Lampard and then Thomas Tuchel, making 28 appearances across all competitions this season.
The Brazilian-born Italian has sat out the current international break due to a knee injury.
