This was the day that Antonio Conte seemed to have run out of ideas.
In a must-win game against bitter rivals, Chelsea were utterly outclassed.
From the moment Tottenham got their noses in front, there was only going to be one winner.
Chelsea failed to have a shot on target in the second half, but Conte waited until the 81st minute to bring on a substitute to try to change the game.
Was he trying to make another point to Roman Abramovich that he does not have the squad depth to compete?
