That is according to former Arsenal defender Martin Keown.
Hazard has gone six league games without a goal after starting the season in virtuosic fashion, notching seven goals and three assists in his first eight games.
The Belgian has casted doubt over his future in west London ever since the summer World Cup, admitting he dreams of a move to Real Madrid.
The Stamford Bridge faithful accepted they may have a case akin to Cristiano Ronaldo’s transfer from Manchester United to Los Blancos on their hands, but that was easier to digest while Hazard was performing well.
The recent dip has correlated with Chelsea’s stutter, which has seen them claim only four of the last 12 points on offer.
A loss to Wolves in midweek, 11 days after losing their unbeaten record to Tottenham, has heaped pressure on Sarri, whose idiosyncratic methods are now under question.
Arsenal legend Keown believes the Italian tactician must shoulder some blame for Hazard’s dip and – more importantly – be the man to stabilise his form.
“Hazard is without a goal in 11 games for club and country,” Keown told MailOnline.
“When such a brilliant player has a dip in form like this, it is up to the manager to push him.
“Maurizio Sarri needs to demand more from him and let him know in no uncertain terms that Chelsea are reliant on him.”
The Blues welcome table-toppers Manchester City on Saturday evening, and Keown feels it is the best game for Hazard to mark his return to form.
“When Eden Hazard is on it, I do not believe there is a defender in world football who could live with him,” the Arsenal legend added.
“Should Chelsea’s season peter out, it could be the last we see of Hazard in the Premier League.
“If he is going to go, let’s see if he can leave a dent in this Manchester City team first.”
