Hazard has been your best player in the absence of Mata in his best position. Mata was arguably more influential in that Champions-League-winning side, although that may have been because his teammates were more average. Mata is world-class; Hazard doesn't currently have the consistency to be.
True.
Hazard has always said about himself and so have i that he needs to work on his consistency. And since December ish he has been sensational every game. If Hazard can be consistent then in my opinion he could be one of the best in the world.
