Just as it seemed the Belgian was getting back to his best, he is now set to miss the next four weeks of action after picking up a muscular injury this week.
Former Manchester United star Dimitar Berbatov does not believe Hazard replicate the form he showed at Chelsea and should consider selling him.
"Real Madrid should consider selling Hazard," Berbatov told Betfair.
"He has had a lot of injuries since he arrived in Spain, and that has prevented him from showing the brilliant football that he played at Chelsea.
"If it was something occasional then it would be a different matter, but the fact is that the player is injured again and again and again, that is a sign that there is another problem that is affecting him.
"Will he be able to regain the form he had and show that the money Real Madrid invested in his was the right decision? Right now, the answer is no.
"It's true that Hazard has only just turned 30 and still has a lot of time to contribute a lot, but this question is one which needs to be asked.
"Hazard has yet to prove anything in Madrid, so it wouldn't be a surprise if he left in the summer."
