Chelsea could find themselves in a defensive crisis this summer with four senior defenders possibly on their way out.
Cesar Azpilicueta, Antonio Rudiger, Andreas Christensen and Thiago Silva are all on deals that expire in June.
It emerged this week that other Blues stars are reportedly 'bewildered' and 'unhappy' that Azpilicueta, who lifted the Champions League trophy back in May, has not seen his contract extended.
While Thomas Tuchel has star full backs Reece James and Ben Chilwell at his disposal and Trevoh Chalobah continues to impress, the quartet are pivotal cogs in his well-oiled machine.
