The pair have struck up an impressive relationship at Los Blancos, playing an integral part in the team's recent upturn in form.
"After having played with him for three or fourth months, I think that, right now, he's the best striker in the world," Hazard said.
"But [also] away from his role as a striker, he makes others better."
Benzema hasn't played for France since 2015 in the aftermath of the so-called 'Valbuena case'.
"I feel for him," Hazard said about the situation.
"It's always easier to play against a team that doesn't have Benzema in it."
