The 23-year-old paid tribute to them and, in particular, to Frank Lampard, who passed on penalty-taking duties to allow the forward to net his third.
Hazard, whose most recent hat-trick was in May 2012 in his last game for previous club Lille, said: "It's a good present. Without the team I'm nothing.
"I just want to say thank you. Thank you, Lamps, for the penalty, because normally it's for him.
"I just said 'if you want it, take it, I don't care'. He said 'no, no'.
"(It is) my first hat-trick in the Premier League. I hope I can do the same another day. I work for that."
