Gary Cahill has revealed he is prepared to quit Chelsea in January, as he grows increasingly frustrated over being frozen out by new head coach Maurizio Sarri.

Cahill has not played a single minute since Sarri’s appointment in July and the former England defender is ready to reluctantly call time on his six-year career at Stamford Bridge.

The 32-year-old has lifted two Premier League titles, the Champions League and the FA Cup since joining from Bolton Wanderers for £7 million in January 2012, and was officially named as club captain last season after John Terry's departure.

His decision to retire from international football after the World Cup was designed to prolong his career at club level, yet it has been a difficult start for the centre-half since Sarri’s arrival.

Cahill has not been included in any of Sarri’s squads for Chelsea’s five Premier League games and was an unused substitute for Thursday’s Europa League tie with PAOK Salonika.

And he has admitted he will consider leaving the club in January, with Watford and Marseille emerging as potential destinations.
