Harry Kane's late brace earned a 3-2 win for Tottenham at home to 10-man West Ham on Saturday, extending the only unbeaten record in the Premier League.
West Ham led the bitter London derby 2-1 after 89 minutes but somehow Spurs roared back to claim victory, with Kane equalising and then putting away a precise injury-time spot-kick in the space of two dramatic minutes to end his team's run of seven games without a win, as Winston Reid saw red late on to compound the Hammers' unexpected misery.
The visitors looked set to claim a derby win thanks to Manuel Lanzini's penalty, Harry Winks having earlier cancelled out Michail Antonio's headed opener by scoring on his Premier League debut.
They did not reckon with the intervention of Kane, who demonstrated his poachers' instinct to equalise on the rebound when substitute Son Heung-min had a shot saved by Darren Randolph.
Referee Mike Dean then pointed to the spot again when Son went down in the box under a challenge from Havard Nordtveit and Kane smashed home from 12 yards to break West Ham hearts and move Spurs within three points of top spot in the Premier League.
West Ham had been on track to record their third win in five league games, but instead they now sit a solitary point above the relegation zone.
Spurs had the ball in the net in the sixth minute, but the goal was correctly ruled out for offside after Christian Eriksen strayed behind the defensive line before smashing in a fine finish.
Kane and Antonio then fired off target from the edge of the area in a frantic opening 15 minutes before the game settled down.
Antonio's header was the only goal of this fixture in March and his 11th headed strike of 2016 put West Ham into the lead after 24 minutes.
Dimitri Payet's deep corner picked out Cheikhou Kouyate, whose header crashed against the crossbar, and when Reid put the ball back into the six-yard box, Antonio was on hand to nod in.
Mauricio Pochettino paired Kane and Vincent Janssen in attack only for Spurs to fail to muster a shot on target in the first half for their second Premier League game in succession, but the hosts were much-improved after the interval and equalised just five minutes after the restart.
Janssen was heavily involved and, although he seemed to control a Danny Rose cross with his arm, Randolph was only able to deflect the Dutchman's powerful shot to the feet of Winks for a dream goal.
Randolph made a fine save with his left boot from Eric Dier's firm downward header after 57 minutes as Spurs cranked up the pressure.
West Ham regained the lead after 68 minutes, Lanzini converting from 12 yards after Dean penalised Janssen for holding Reid.
Slaven Bilic must have thought his team were set to record a valuable win away to their fierce foes, but Kane was on hand to pounce and equalise on the rebound after Randolph saved Son's initial shot with a minute to go in normal time.
Nordtveit then tripped Son inside the area to give away a penalty, tucked away with aplomb by the ice-cool Kane to spark wild celebrations among the home fans at White Hart Lane.
