Jose Mourinho's men took advantage of Arsenal's 5-1 drubbing at the hands of Liverpool and Manchester City's goalless draw with Norwich City to leapfrog their title rivals.
Hazard was the hero, the 23-year-old producing a virtuoso performance and taking his goal tally for the season to 14 with an impressive treble. The Belgian opened the scoring midway through the first half with an emphatic finish and his second quickly followed as he rounded off a superb Chelsea breakaway after 34 minutes.
That ended the game as a contest but the former Lille man applied the gloss to a fine display with a penalty just after the hour mark.
