Well, that certainly did not go according to plan.
The first half was largely dominated by the Blues, who went into the break with a 1-0 advantage.
However, despite missing Gareth Bale and Mousa Dembele, Spurs entered the second half on a mission and turned their deficit into a 2-1 lead.
In the end, though, Chelsea had too much for Tottenham, and they kept their place at the top of the league table.
For Spurs, the loss provided only a moderate setback, as they kept their fifth-place spot.
So how poor were Tottenham on the day? And who stood out as a bright spot in the loss?
Here is a rating of every Spurs player's performance.
