Heung-Min Son's late piledriver cancelled out Pedro Obiang's stunning effort to spare Tottenham's blushes in a 1-1 draw with West Ham at Wembley.
The relegation-threatened Hammers spent the majority of the game on the back foot but Obiang's 70th-minute thunderbolt - their first shot on target - moved them to within reach of an unlikely victory.
But Son's 10th goal of the season salvaged a point for Spurs, who remain fifth in the Premier League. David Moyes' men extended their unbeaten Wembley run to nine games, and climbed up to 15th in the table as a result.
Tottenham: Lloris (5), Aurier (6), Vertonghen (6), Sanchez (6), Davies (6), Dier (6), Sissoko (5), Alli (6), Eriksen (6), Son (7), Kane (6).
Subs: Lamela (5), Wanyama (5), Llorente (5).
West Ham: Adrian (7), Zabaleta (7), Ogbonna (7), Reid (7), Rice (7), Obiang (8), Kouyate (6), Masuaku (6), Lanzini (6), Noble (6), Chicarito (6).
Subs: Carroll (6), Ayew (6).
Man of the Match: Pedro Obiang
West Ham's goal was under threat from the first whistle. Declan Rice was forced to hook a Kane effort, which flashed across goal, away on four minutes before a flap from Adrian at the resulting corner presented Eric Dier with a chance, but his effort was blocked.
The Hammers weathered the early Spurs onslaught but remained firmly on the back foot; the offside flag coming to their rescue as Kane's deflected effort was correctly ruled out.
Kane drew Adrian into action with the game's first shot on target on 28 minutes, and Son and Eriksen tested the Hammers goalkeeper soon after as Spurs cranked up the pressure.
However, West Ham reached the interval unscathed, with Kane unable to take Serge Aurier's 34th-minute knock-down into his stride before Eriksen's deflected effort drew a fingertip save from Adrian.
Despite having just a 48-hour turnaround from their last outings, both managers made just three changes apiece. Mauricio Pochettino recalled Harry Kane, Serge Aurier and Moussa Sissoko following Spurs’ win at Swansea, while David Moyes drafted in Mark Noble, Declan Rice and Javier Hernandez – Andy Carroll dropped to the bench despite his two goals against West Brom.
A misplaced pass from Davinson Sanchez released Javier Hernandez through on goal shortly before the hour, but the Spurs centre-back showed great pace to recover.
Pablo Zabaleta's last-gasp intervention denied Kane at the end of a flowing 67th-minute attack, with Alli heading the rebound over, and West Ham's dogged defensive display was soon rewarded as Obiang's thunderous strike beat Hugo Lloris all ends up.
Spurs stirred but required a moment of brilliance to break West Ham's resolve as Son's swerving 25-yard effort found the top corner. The hosts then pushed for a winner, but the Hammers held on for a valiant point at the home of their fierce rivals.
- In four London derbies in all competitions under David Moyes, West Ham have managed just three shots on target. However, they've scored two of them, and have lost just once (W1 D2).
- Pedro Obiang's strike in the 70th minute was West Ham's first shot of any kind in this match.
- Son Heung-min has been directly involved in 12 goals in his last nine home games for Tottenham in all competition (7 goals, 5 assists).
- Spurs have never lost a Premier League game on a Thursday (P11 W6 D5 L0) - it's the highest number of games played by a team on a specific day without defeat in the competitions history.
- Harry Kane has scored just three goals in his last 10 Premier League London derby matches, failing to find the net on eight occasions in that run.
- After a run of 13 defeats in 16 Premier League games against 'big six' opponents (W1 D2), West Ham are unbeaten in their last three against them (W1 D2).
Mauricio Pochettino: "We gave everything to win. We dominated the game. Yes, sometimes things like this happen in football; you push, force and have chances to score, but it's impossible to score. I'm happy with the effort and performance having had 48 hours to prepare."
David Moyes: "The biggest thing for us was how long we didn't allow Spurs to score. I didn't want to come here and get beaten by four or five. I would love to have the players Spurs have. At the moment we don't. My job as the coach is to find a way to get results, which we did."
Man of the Match - Pedro Obiang
There seemed nothing on when Obiang collected the ball on the left flank some 30 yards from the Tottenham goal, but the Spaniard stunned Lloris with a rising rocket of strike which flew into the top corner. West Ham's first shot of the match was worth the wait, and so nearly claimed a victory their dogged defensively display deserved.
