Chelsea defender Marcos Alonso emerges as a January target for Barcelona, according to a report.
The Catalan giants are said to be targeting a new left-back before the January transfer window closes to provide competition for Jordi Alba, with Junior Firpo's future at the club unclear.
According to Mundo Deportivo, Alonso has been identified by Ronald Koeman's side as a possible arrival in the final stages of the mid-season window.
The 30-year-old has only made three appearances for the Blues during the 2020-21 campaign, while he has not played a single minute of football for the club since the end of September.
Alonso has made over 150 appearances for his current side in all competitions, though, and still has two and a half years left to run on his contract at Stamford Bridge.
Valencia's Jose Gaya is also allegedly being considered by Barca this month.
