Chelsea are reportedly keen to move on either Emerson Palmieri or Marcos Alonso during the January transfer window.
Both Emerson and Alonso were linked with exits over the summer, but the deadline passed with the two defenders still at Stamford Bridge.
Ben Chilwell has become Chelsea's first-choice left-back since his arrival from Leicester City, and Emerson has been restricted to just one Premier League appearance this term.
Alonso has featured on three occasions in England's top flight, although the Spaniard has not been used since being replaced at the interval of the 3-3 draw with West Bromwich Albion at the end of September.
According to Goal, the Blues will attempt to sell a left-back at the start of 2021 as head coach Frank Lampard looks to trim his squad.
Juventus and Inter Milan are said to be monitoring the developments surrounding both players.
