Eden Hazard said it is "impossible" for him to leave Chelsea in January, but is keeping his options open for the summer.

Chelsea are desperate to sign Hazard to an extension as he enters the final season of his contract. The club is prepared to make him the richest player in club history.

Hazard said in September that a move to Real Madrid was his "dream."

"Impossible. I don't see myself leaving in January, for the club, for the fans," said Hazard about leaving Chelsea for Real Madrid in January.

"It's possible [that he could leave in the summer], as I repeat every time, but it's also possible I stay at Chelsea for my whole career.

"For the moment, as I have already said, I'm focusing on Chelsea this year. I have a year on my contract after this year. If there is no contract extension, of course [he would be sold]."
