Elseid Hysaj's agent has revealed that the Napoli right back could reunite with Maurizio Sarri at Chelsea next month at the expense of Davide Zappacosta.
Sarri left the Serie A side to become Blues' manager and took midfielder Jorginho with him to Stamford Bridge.
Napoli president Aurelio De Laurentiis blocked Chelsea from signing Hysaj over the summer, his agent Mario Guiffredi revealed in October.
But the 24-year-old's switch to the Premier League side could now be back on.
‘I can’t rule out resuming negotiations with Chelsea in January,’ Guiffredi told Radio Crc.
‘We know there was contact in the summer because Sarri wanted him, and we also know that Zappacosta is not to the liking of the coach.
‘We’ll see how it goes, anything could happen.'
Hysaj has made 16 appearances for Napoli so far this season, while Chelsea right back Zappacosta has played in just 8 matches.
Sarri's Chelsea face league leaders Manchester City at the weekend looking to return to winning ways following defeat at Wolves.
