Napoli close to deal for Cagliari defender
Sky Sport Italia are reporting that the two clubs met on Friday and are set to agree on a €13 million for Astori.
It is believed that he would sign a four-year contract with the Partenopei worth €1m per season.
Earlier last week, Cagliari president Massimo Cellino stated that he would let Astori leave the club if he requested a move and it appears the Italian international has acted on those words.
The 26-year-old has been with the Rossoblu since 2008, appearing in 144 matches.
He also featured for the Italian national team over the summer during the FIFA Confederations Cup.
