Harry Kane won a penalty and scored with the last kick of the game to earn Tottenham a draw against West Ham.
Kane’s 96th-minute penalty was saved but he reacted quickest to give Spurs an unlikely point at White Hart Lane.
West Ham had led 2-0 through goals from Diafra Sakho and Cheikhou Kouyate with just nine minutes left to play.
Danny Rose’s mis-hit long-range shot set up the comeback before Kane, who was felled by Alex Song, pounced to score his 24th goal of the season.
Spurs boss Mauricio Pochettino made six changes to the side that drew 1-1 with Fiorentina in the last 32 of the Europa League in midweek, as he prepared for the second match of a demanding schedule of six games in 17 days that includes Thursday’s return leg in Florence and next Sunday’s League Cup final against Chelsea.
With Spurs also chasing Champions League qualification via a top-four finish in the Premier League, Pochettino recalled top-scorer Kane for this London derby but opted to rest his other star performer this season, Christian Eriksen.
Spurs started in typically quick fashion as Nabil Bentaleb twice tested West Ham goalkeeper Adrian with long-range efforts before Kane struck the post in an opening 10-minute spell in which Spurs enjoyed 82% possession.
However, it was the robust-tackling Hammers who took the lead on 22 minutes when Mousa Dembele lost possession on the edge of his own box and midfielder Kouyate rose between two defenders to powerfully head home Aaron Cresswell’s cross.
That proved to be Dembele’s key contribution to the match as he was replaced at half-time by Eriksen, who had started Tottenham’s last 34 Premier League games and notched 11 goals and four assists in all competitions this season.
But it was West Ham who continued to create the better chances and after Sakho had squandered a one-on-one with Hugo Lloris, the Senegal striker made no mistake at the back post on 62 minutes, squeezing in Mark Noble’s cross for his 11th goal of the season.
West Ham looked set for a first victory in four Premier League games to ease the pressure on manager Sam Allardyce, whose future had been the subject of speculation following a humiliating 4-0 FA Cup loss to West Brom in midweek.
However, Spurs had other ideas and after Rose had halved the deficit with his fortuitous strike, Kane once again stepped forward as Spurs’ saviour this season.
The striker went down in the box under the slightest pressure from Song and after seeing his penalty saved by Adrian kept his composure to slot home the rebound for the Premier League’s sixth-placed side.
