Spurs struggled to break down a stubborn home side in the first half but got their breakthrough when Joel Ward turned James Maddison’s cross into his own net in the 53rd minute.
Heung-min Son’s eighth goal in ten League games capped a fine move and sealed the points for Spurs, who remain unbeaten and increasingly feel like the real deal.
Jordan Ayew set up a nervy finale by rifling in a brilliant strike in stoppage time but Spurs held on to move five points clear for the first time in Premier League history.
Here’s how we rated the Spurs players at Selhurst Park…
Guglielmo Vicario 7
Maintained his fine form with sharp stops from Jordan Ayew and Odsonne Edouard in the first half and commanded his area well.
Pedro Porro 6
Involved in the build-up to the opening goal and assured in possession but caught out for Ayew’s late goal.
Cristian Romero 8
Booed throughout for the crime of being fouled by Edouard but composed on the ball and did not put a foot wrong at the back.
Micky van de Ven 8
His pace was important in sweeping up, particularly behind Davies in the first half. Lightning quick and imposing.
Ben Davies 4
His pace was exposed once or twice by long balls, forcing van de Ven to cover, and he did not look comfortable inverting. Spurs missed Destiny Udogie.
Pape Sarr 8
