The Belgian was set in over the top by Cesc Fabregas, who also enjoyed a fine game, and from that moment there was no doubt as to what the result would be.
Hazard skipped back inside Ahmed Hegazy, before firing past a helpless Ben Foster and into the far corner.
It was the ciing on the cake of a sensational display from the winger, who assisted Chelsea's first before doubling their lead soon after.
