And the Belgian schemer was, in the end, one of the big reasons why Mauricio Pochettino's side bowed out of the race at Stamford Bridge on Monday night, ensuring Leicester City are champions.
The 25-year-old, a half-time sub, injected a fresh sense of life into the Blues, who were trailing 2-0 from the first half following goals from Harry Kane and Son Heung-min as Spurs looked on course for the win needed to move five points behind Leicester.
But Gary Cahill increased anxiety levels in the away end on 58 minutes by reducing the arrears, before Hazard, with seven minutes to go, curled home a wonder strike to leave Hugo Lloris with no chance and Tottenham's title bid on the brink of collapse.
At full time, there was something of a melee at the entrance to the tunnel, with staff on both sides - including Pochettino - in the mix. It was a fitting end to a feisty encounter which saw 12 players booked - nine of which were Spurs players.
