Christian Eriksen came off the bench to score a 91st-minute winner for Tottenham and seal a 1-0 victory over Burnley at Wembley on Saturday.
Burnley defended resolutely and wasted time where possible, and looked to be set for a point after Joe Hart twice denied Erik Lamela.
However, Harry Kane picked out Eriksen in stoppage time, and the Dane fired beyond a helpless Hart to end Burnley’s resistance in dramatic fashion.
The victory ensures Spurs remain five points behind leaders Manchester City, while Burnley are teetering two points above the relegation zone in 17th.
The wet conditions made for a sluggish start at Wembley, as a Spurs side who made five changes from the midweek draw at Barcelona found it difficult to break down Burnley’s five-man defence.
However, the hosts did go close in the first half, with Lucas Moura dinking a first-time volley just wide before Lamela’s stabbed effort was saved by Hart.
Kane also had a penalty claim waved away between those chances, with referee Graham Scott seeing nothing wrong with James Tarkowski’s challenge on the Spurs striker.
A wayward Ashley Barnes header was Burnley’s best opportunity of the half, and the forward went close shortly after the break when his volley was blocked by Toby Alderweireld and then Kane.
Burnley’s tactics continued to frustrate Spurs, with Robbie Brady and Phil Bardsley both booked for time-wasting, and Mauricio Pochettino sought to bring on Eriksen and Heung-min Son to change his side’s fortunes.
Hart then got down well to keep another Lamela attempt out with 15 minutes to go, but after Son fired wide from an acute angle, Eriksen finally broke Burnley’s resolve with a sweeping effort at the near post.
