Michael Essien could leave Chelsea in the transfer window, according to his agent.

The Ghana midfielder spent last season on loan with Jose Mourinho at Real Madrid, but has managed just three Barclays Premier League appearances this term.

Essien joined Chelsea from Lyon in 2005, moving on to claim two Premier League titles, four FA Cups and the Champions League.

The 31-year-old has been omitted from Chelsea's Champions League squad so far this season.

Agent Fabian Piveteau believes that could help pave the way for a move to another big European club during the January window.

"He could leave Chelsea this winter," Piveteau told French radio station RMC.

"Several major European clubs playing in the Champions League were informed and the situation should settle down within the next 10 days.
