Chelsea are ready to sign Elseid Hysaj in January and send him back to Napoli on-loan.
Calciomercato.com says Chelsea plan to convince Napoli into selling Hysaj in January by sending him back to the Italians on loan until the summer.
Maurizio Sarri would like to be reunited with the Albanian right-back.
The deal will cost the Blues about €50m (£45m), which would be comparable to Manchester City's deal to sign Kyle Walker from Spurs.
Hysaj's arrival would see Victor Moses and Davide Zappacosta moved out by Chelsea.
