Jeffrey Schlupp capitalised on a Hugo Lloris error to snatch a point for Crystal Palace against Tottenham, as it ended 1-1 at Selhurst Park.
After an open start at Selhurst Park, where both sides had chances, Spurs drew first blood in the 23rd minute and it was Harry Kane and Son Heung-min that again combined.
Son teed up Kane who hit a swerving 25-yard shot that went straight through Vicente Guaita as the duo combined for the 13th time in all competitions this season.
Palace had put Spurs under endless pressure in the second half and got their reward in the 81st minute as Schlupp rammed home a loose ball from a free-kick.
It extended Tottenham's unbeaten run to 11 league games but they were made to work hard throughout.
They completely went into their shell after Kane and Son Heung-min had combined for the 32nd time in the Premier League and only came back to life in the final 10 minutes when Ben Davies hit the crossbar and Vicente Guaita made two good saves.
The draw means Spurs would be usurped at the top of the table by Liverpool if the Reds won at Fulham later on Sunday.
Spurs had two good early chances, as Guaita denied Tanguy Ndombele with a superb low stop before palming away a Kane header.
But the Spanish goalkeeper was at fault as Spurs took the lead in the 23rd minute and there was little surprise in the two players involved.
Son rolled the ball to Kane and the England captain unleashed a 25-yard effort that swerved and went through the grasp of Guaita, who should have kept it out. Kane was not complaining as he celebrated his ninth league goal of the campaign.
Palace’s response was spirited as they continued to ask questions of the visitors, whose mean defence made it difficult for them, and they were ultimately rewarded when Lloris could not hold a free-kick into the box and Schlupp fired home the loose ball.
That finally prompted Spurs back into life and Guaita redeemed himself in fine fashion as Mourinho’s men pushed for a winner.
After Davies’ overhit cross cannoned against the crossbar, Guaita did well to save Kane’s header.
But he saved his best until last, flinging himself to his right in added time to spectacularly keep out Eric Dier’s free-kick, which was bound for the top corner
