The French striker impressed on his first start on Monday evening, claiming an assist for the opening goal against West Bromwich Albion and being heavily involved throughout his hour on the field.
Giroud has helped lift some weight off the shoulders of Alvaro Morata, who has struggled for fitness of late and failed to score in seven matches since December 26, while also providing a slightly different option to link play up top.
Speaking to reporters after his side's 3-0 win over Albion, Hazard admitted to being pleased by the late January addition.
"He's a good guy, a good target man and he can score a lot of goals. He's a good point of reference but we have him, we have Alvaro and I can also play as a striker."
Hazard scored two of Chelsea's goals on their return to winning ways, while Victor Moses also chipped in with his second of the season.
