Eden Hazard’s form has been so poor this season because he is not happy at Chelsea, according to Glenn Hoddle.

The former Stamford Bridge manager gave his verdict on the Belgian as he delivered another laboured display in Chelsea’s goal-less draw at Manchester United on Monday night.

Hiddink was used in the striker role by Guus Hiddink at Old Trafford in the absence of unavailable trio Diego Costa, Loic Remy and Radamel Falcao but failed to break his goals duck for the season.

Hazard has not scored in 26 matches in the current campaign for the Premier League champions, and has failed to supply an assist in his last 11 league matches.

Speaking to BT Sport, Hoddle said he is a big admirer of the reigning Footballer of the Year but is convinced that his performances are not not physical.

“I don’t know if he is 100 per cent happy at Chelsea,” observed the club’s former manager. “His problems seem to be in his head.”

Hazard was a second-half substitute for the Blues in their 2-2 draw against Watford on Boxing Day after recovering from a hip injury, and was restored to the starting line-up on Monday night after convincing new manager Guus Hiddink he was ready to play from the start.
