Chelsea could make a fresh move for Sevilla defender Jules Kounde with Thomas Tuchel keen to bolster his defensive options.
The German was unable to land his top defensive target on transfer deadline day but he remains a firm admirer of the French international.
Chelsea thought they were closing in on a deal for Kounde in the final days of the window but saw their hopes end when Sevilla insisted on his release clause of around £68million being met in full.
Chelsea will monitor Jules Kounde ahead of a potential move in January or next summer
The centre back was heavily linked with the Champions League winners throughout the summer transfer window and was reportedly furious that he was not granted a move to the west London club.
