Chelsea's quest for the Premier League's all-time single-season winning streak came up a game short, as Dele Alli's two goals gave Tottenham a 2-0 win over the Blues, snapping their streak at 13 games.
Tottenham crept into third place with the win, its fifth straight, as it is level with Manchester City (but ahead on goal differential) and leads another London rival, Arsenal, by a point through 20 matches.
The match was the final one between Tottenham and Chelsea this season, with Chelsea coming from behind to take the first meeting back in November, 2-1.
Eden Hazard had a golden chance to put Chelsea ahead early on in Wednesday's encounter, but he pulled his fifth-minute chance just wide of Hugo Lloris's post to let Tottenham off and keep things scoreless.
Following a Chelsea counterattack that sputtered, Diego Costa and Pedro had words, at length. The latter's run created a logjam of space in the box instead of a lane for which Diego Costa could pass or shoot, and the two Spain internationals engaged in a briefly volatile discussion about what happened.
Soon after, Christian Eriksen then had a chance to open the scoring, putting a right-footed drive just wide of the left post and a diving Thibaut Courtois with over 20 minutes gone in the match.
Courtois came up again in the 39th minute, reacting quickly to swat away Eric Dier's header following a cross from Danny Rose.
The goalkeeper could do little to prevent Alli from scoring the opener just before halftime, though. Eriksen found Alli with space in the center of the box, and the rising English star headed across the goal to give Spurs the lead in first-half stoppage time.
Alli was at it again just after halftime off another precise ball from Eriksen, which he met with a difficult header to give Tottenham a 2-0 lead. The 54th-minute goal meant Alli has scored two in each of Tottenham's three games over the holiday slate, and it marked the fourth straight game in which he's scored. He came off in the final minutes to a raucous roar of approval from the Spurs fans at White Hart Lane.
The teams return to league play on Jan. 14, with Tottenham hosting West Brom, while Chelsea plays at defending champion Leicester City.
Chelsea maintains a five-point lead over Liverpool at the top of the table, with Tottenham seven points behind.
