Hazard reminded the Blues what they will be missing if he leaves for Real Madrid this summer with a breathtaking display during the 2-0 victory over West Ham on Monday night.
The Belgian waltzed through the Hammers’ defence to score a wonderful solo goal, before doubling his tally with a fine strike late-on.
It was the kind of match-winning individualism that Stamford Bridge has become used to. After all, Hazard has been directly involved in 49 per cent of the club’s Premier League goals this season.
But Chelsea boss Maurizio Sarri has admitted there is very little he can do to stop the 28-year-old from moving to Madrid if his heart is set on the Bernabeu.
Arsenal were equally powerless when Barcelona came knocking for club legend Henry in 2007, which signalled the beginning of a prolonged period of mediocrity for the Gunners.
And former Blues striker Cascarino, who expects Hazard to leave this summer, believes the potential move could have a similar effect.
