Chelsea have reportedly turned their attention to Paris Saint-Germain full-back Layvin Kurzawa, with the Blues hoping to secure a loan deal.
The Blues have been in the market for cover in this position due to Ben Chilwell and Reece James suffering injuries, with the left-back out for the entire season.
The defending European champions had been linked with Lucas Digne at the start of the window, but he has since joined Aston Villa, leaving Thomas Tuchel's side still searching.
According to Sky Sports News, Chelsea are now interested in bringing in Kurzawa on a loan deal until the end of the season in order to provide some cover for Marcos Alonso.
The PSG full-back previously worked with Tuchel during his time in charge of the French outfit, and the defender has been with the club for six and a half years.
The 29-year-old signed a four-year contract extension in 2020, and has made 140 appearances during his time with the team.
