Chelsea are keeping tabs on France international Jonathan Clauss as they believe he could be a worthy replacement for Cesar Azpilicueta, according to reports.
Thomas Tuchel is said to be a long-term admirer of the 29-year-old from RC Lens - having initially stated his interest in the wing-back when he first arrived at Chelsea.
The Premier League giants could now acquire his services for as little at £10million this summer, according to Goal.
