Hazard has been a key player for the title chasers this season, but Mourinho believes that Hazard can continue to develop as a player by learning from Lampard, who is in his 13th season at Stamford Bridge.
"I think Eden has great examples to follow at Chelsea," the Portuguese coach told Yahoo Sport. "He doesn't need to look outside the club to find the best examples to follow.
"We have Frank Lampard who is 35 and is, of course, at the end of his career. There is no better example of a professional player than him for Eden and everyone else."
Chelsea return to action in the Premier League against Crystal Palace on Saturday.
