Hazard joined Real from Chelsea in the summer for an initial £88.5million fee which will rise to £130m with add-ons.
Although Lampard has been quick to play down any suggestion that his side could challenge Liverpool and City for the league title, if they are able to beat the reigning champions this weekend they will certainly be in the conversation.
Hazard told Sky Sports: “Of course I think [Chelsea can win.] It's not going to be easy.
“It's hard to play there. Last time we played them we lost 6-0, so bad memories for me and for Chelsea as well.
“But I think this season they are really good. They are really young, but they are really good, so why not go there and win the game?"
