Branislav Ivanovic has not yet been offered a new contract by Chelsea.
The 31-year-old Serbian defender is out of contract at Stamford Bridge next summer but is yet to be offered an extension by the English champions.
According to the Daily Mail, a number of Premier League rivals are monitoring Ivanovic's situation in West London, especially seeing the Blues are chasing Everton youngster John Stones.
Some reports this week are speculating that Ivanovic could be dropped this week, following Chelsea's poor start to the new season, with Cesar Azpilicueta set to replace him at right-back with new signing Abdul Baba Rahman to slot into the Spaniard's vacancy left-back.
