The Blues legend is still without a club having terminated his Real Madrid contract at the start of the summer.
Chelsea were briefly linked with re-signing the club icon but Hazard made his return to West London as a supporter instead.
He watched on as the points were shared with Luis Diaz and Axel Disasi finding the net.
But Chelsea fans were in awe of Hazard’s presence, as one said: Eden “Hazard at Stamford Bridge in the box in the Shed End. Proper Chels.”
Another added: “Eden Hazard is at the game today. Proper Chels man, love him.”
Hazard has most recently been subject to interest from David Beckham’s Inter Miami, who landed Lionel Messi this summer.
But the forward is understood to have turned down the offer from the Florida outfit.
According to Voetbalkrant, the 32-year-old has no interest in leaving Europe for the MLS.
It has even been suggested Hazard could RETIRE if he fails to find a new team.
