The striker joined the Blues from Marseille in the summer and has adjusted well to life at Stamford Bridge with a little bit of help from his fellow compatriot.
"He's a top man," Hazard told Chelsea TV of the 22-year-old.
"He is learning a lot. He is trying to speak English. I am helping him, I don't know if I am a good teacher but I try. He gives everything on the pitch and in training. In him and Diego (Costa) we have two very good strikers.
"Sometimes we play with one, sometimes with two. It's difficult for him to sometimes be on the bench but he is still young, he has a lot to do with Chelsea, and I hope he will score a lot of goals."
