Iliman Ndiaye scored a superb late winner as Championship side Sheffield United stunned Tottenham to progress to the quarter-finals of the FA Cup.

As the game looked to be heading to extra time, substitute Ndiaye weaved past a couple of defenders before beating Fraser Forster with a low strike at the near post.

Tottenham, who beat Chelsea at the weekend to boost their hopes of a top-four finish in the Premier League, looked off the pace as they struggled to test Blades goalkeeper Wes Foderingham.

Richarlison blasted a shot over the bar from close range but failed to make an impact, forcing Spurs to turn to Harry Kane as the second half wore on, but even the club’s all-time top scorer was unable to really test a fired-up Sheffield United.

Kane had just the one real chance to score when he rose unmarked to meet a cross in the final few seconds but somehow headed wide.

The Blades – who are chasing promotion to the Premier League – then held firm to secure a famous win.

Spurs assistant manager Cristian Stellini said afterwards: “If you don’t win a game like this its because something was not perfect and today our energy was not enough to put the opponent in a great difficulty.

“We had opportunities to score, but now we have to analyse the goal we conceded. In the moment if you concede a goal you need time to recover.

“There was more energy from the changes, but we have to improve a lot.

“I can only apologise to the fans for our performance and they deserve much more than this.”
