Torino defender Angelo Ogbonna has become Napoli's top transfer target of the January transfer window.
Gianluca Grava's serious knee injury has prompted the club to step up its efforts to reinforce the defence.
Torino value Ogbonna at €10m and Napoli President Aurelio De Laurentiis is eager to reach an agreement.
In the meantime, Napoli have halted Fabiano Santacroce's exit in order to retain an alternative as cover.
Napoli have also expressed an interest in Bologna defender Miguel Britos, although he is apparently not for sale.
