Chelsea are considering a £10m deal for Lens defender Jonathan Clauss, according to Goal.com
The Blues have been keeping close tabs on the full-back for at least 12 months ahead of a potential move to sign the Frenchman.
The report adds that Chelsea are lining up a move to sign the 29-year-old defender provided certain conditions with regards to the deal.
The full-back is set to become a free agent in June 2023 and the Ligue 1 outfit are under pressure to cash-in this summer or lose him on a free transfer.
The Premier League giants are looking to fill the void left by Antonio Rudiger and Andreas Christensen so Clauss could fit the bill.
Chelsea could also lose Cesar Azpilicueta on a free transfer which would speed up a deal for Clauss, who scored five goals and registered 11 assists in 37 appearances in the French top flight last season.
