It's really unfortunate how Hazard career went out in the middle of other players who aspired to be at a club as big as Real Madrid. But for Hazard he was just unlucky. Injuries hit him for quite a long time, so that Ancelotti was reluctant to put him on the field. Now the opportunities are dwindling for him and I'm quite concerned considering at Chelsea of course Hazard performed brilliantly.
I think he should leave Real Madrid if he wants to get play more minutes because that could save his career. During this season he has always been a substitute player and that is not a good thing for him considering he was so successful at Chelsea. his relationship with Ancelotti has also been less than harmonious after he was placed in second choice in every game, now from this it is likely that this season will be his last season with real madrid and if he leaves it is most likely a better choice.
Hazard was unable to compete with Vini and Rodrygo and Benzema on the Real Madrid front lines, this was because he was often plagued by injuries which made his career slowly fade.
