The central defender has struggled to get regular playing time under new manager Maurizio Sarri this season following the Italian’s appointment as Antonio Conte’s successor at Stamford Bridge.
The 32-year-old is yet to make a single first team appearance for Chelsea FC so far this term, with Sarri instead opting to partner David Luiz and Antonio Rudiger in the heart of his four-man defence.
It remains to be seen whether the 32-year-old will be able to force his way into first-team affairs at Stamford Bridge this season under the new manager.
But the England defender has now openly admitted that he may look to leave the west London club in the January transfer window.
Speaking in an interview quoted by Metro, Cahill said: “I don’t want to jump the gun but as things stand at this time, probably, yes [I might have to leave in January].
“Whatever my future holds, in terms of the club, and the relationship I have with the club and the fans, it will have been a huge part of my footballing life.
“I’ve got maximum respect for everybody here. I realise that sometimes you have to make tough decisions and football doesn’t wait for people.
“Sometimes you have to make those decisions to keep going and progressing.”
Meanwhile, Chelsea FC are currently preparing for their Premier League trip to West Ham United in the Premier League on Sunday afternoon.
The Blues are aiming to pick up the three points as they look to continue their 100 per cent start to the new campaign under Sarri at Stamford Bridge.
Chelsea FC have won all of their Premier League games so far as they look to try and challenge for the title this term.
