The 21-year-old has already proven a hit at Stamford Bridge this season after a bright start to the new campaign after moving from Lille in the summer
Despite his tender age, Hazard has already represented Belgium 29 times at international level, but in order to reach his full potential, Collin argues that he must improve his all-round game.
"He has technique, explosiveness and positioning. At some point he will have to work on defending, and he has no choice with that," told Nieuwsblad.

"The learning process is slow but good. If Messi should work for the team and defend, then I see no reason why Hazard should not do likewise."
There were some words of encouragement for the 21-year-old, though, with Manchester City captain and international team-mate Vincent Kompany impressed with how quickly Hazard has slotted into life in the top flight so far this term, adding that everyone needs to be patient with the youngster.
"People always talk about how difficult it is to adapt to the Premier League because it is physical and quick," Kompany told reporters.
"It just takes some time usually so it's remarkable for him to show so much in such little space.
"Players like Eden only make our team stronger which is a good thing and the crazy thing is I still think he has much to room to progress."
Hazard was linked with a move to City all summer, but the talented playmaker opted to join Chelsea instead and Kompany believes that as long as he keeps up his form up at his new club, then that can only benefit the national side in the future.
He added: "I wish him the best, if he does well for his club and if it is the club which is best for him, then I know he will do well for the national team and that’s the most important thing for me."
