Despite this, Wilmots says that Hazard can be happy with his progress to date, which can now be used as a springboard for further success.
"Hazard is rising higher and higher," the Red Devils boss told Goal.com. "He was at Lille for two years and was already one of the best players in France. He won the league and the cup - so he already had success.
"He started early, when he was only 17 years old. I already knew him back then. And now he is 23 and a top star at Chelsea. But he has to score more goals.
"That goes for Chelsea and the national team. Eden keeps marching on and what he has done is amazing, considering his age."
Hazard has scored four goals in 13 appearances for club and country so far this season.
