The Belgium international ended a 26-game run with a brace in Chelsea's 4-1 victory over Bournemouth at the Vitality Stadium last weekend.
Hazard's first Premier League goals of the season were a timely return to form ahead of the crunch London derby against Spurs at Stamford Bridge.
The 26-year-old moved to the defending Premier League champions in a £32m deal from Ligue 1 Lille following Chelsea's Champions League success in 2012.
The Belgian forward scored a hat-trick against Nancy in his final Ligue 1 game before his big-money move to the Premier League side.
And Hazard posted a photo of his hat-trick boots on his Instagram page ahead of Monday night's game against Tottenham.
He wrote: "SCORED A HAT TRICK IN MY FINAL GAME AT LILLE WEARING #MERCURIAL. WHAT'SHAPPENED @NIKEFOOTBALL?"
Chelsea are in 10th place and 22 points behind Premier League title contenders Tottenham ahead of Monday's London derby.
