Preston v Tottenham: FA Cup fourth round – live | FA Cup

85 minutes: Son stares into a world of (physical) pain as he takes his place on the Spurs bench. If he landed a blow, I didn’t notice.

85 minutes: Replacement of Tottenham: Bryan Gil in place of Son.

84 mins: Freddie Woodman quickly leaves his line to recover a cross from Ivan Perisic.

81 mins: Two classy moments from Son Heung-min separate the teams and brightened up an otherwise fairly dreary game in Deepdale. Does the double mark a return to form for the likeable South Korean, or will it be a false dawn like his hat-trick against Leicester in mid-September? If he wants to bring another match ball home, he will have to act quickly because he is about to be substituted.

79 mins: Corner Preston. Fraser Forster claims the high inswinger confidently under pressure from Tom Cannon, who positioned himself close to the Tottenham goalkeeper’s toes on such set pieces.

77 minutes: Preston double substitution: Alvaro Fernandez and Daniel Johnson replace Robbie Brady and Ali McCann.

75 minutes: Davinson Sanchez heads in a Preston free-kick from a deep clearance at the edge of the Spurs penalty area.

70 minutes: Replacement of Preston: Ben Woodburn in place of Ryan Ledson. Triple substitution of Tottenham: Oliver Skipp and Emerson Royal in place of Bentancur and Doherty. Arnaut Danjuma is also in the running for his debut in place of Ryan Sessegnon.

Spurs double their lead. With his back to goal in the Preston penalty area, Son takes a fine pass around the corner from Perisic. With a deft turn, he sends Preston defender Jordan Storey into Deepdale’s parking lot before shooting past Freddie Woodman.

67 mins: From the left touchline, Ryan Ledson tries to send a cross into the Tottenham penalty area. His flow is mediocre and the ball is cleared by Yves Bissouma.

65 minutes: With his back to goal, Ivan Perisic passes Liam Lindsay and wins a header from around eight yards from Preston’s goal. His looping effort threatens to dive under the crossbar but Freddie Woodman stops it.

63 mins: Preston wins a free kick about 40 yards from the Tottenham goal. Alan Nrowne floats the ball to the left and it returns to the front of the penalty area. Tottenham goalkeeper Fraser Forster gathers.

62 mins: Preston responded well to the adversity brought on by Son. From the edge of the Spurs penalty area, Ben Whiteman tries to curl the ball inside the left upright but sends his effort fizzling narrowly.

61 mins: Preston striker Tom Cannon is booked for a blatant dive at the edge of Tottenham’s penalty area. He expected contact from Japhet Tanganga, who was nearby, but he never came.

59 mins: Alan Browne wins a corner for Preston, his attempted cross ricocheting off a defender. Robbie Brady tries to send the ball into the mixer but his delivery is devilishly poor. He fails to extricate the first man.

58 mins: Andrew Hughes sends the ball forward, Tom Cannon wins the header and sends it towards the penalty area. Evans cannot access it.

56 mins: Sessegnon has a cross attempt blocked by Alan Browne. Corner for Tottenham. Son and Perisic take it short and the South Korean creates an angle to drive the ball into Preston’s box. It’s erased.

55 mins: Preston makes a rare attacking outing in the Spurs half but is unable to carve out an opening. Sessegnon recovers the ball for the visitors.

54 mins: Preston wins a free kick down the halfway line and Robbie Brady sends the ball floating into the Tottenham penalty area. It’s erased.

52 mins: It was a wonderful strike from Son, who caught a pass in a central area, picked his spot, then sent an unstoppable shot into the bottom left corner.

Spurs lead! It’s third time lucky for Son, who launches a long-range left-footed curling effort into the bottom corner at least 25 yards out. Freddie Woodman saw his late shot and didn’t come close.

49 mins: Clement Lenglet shoots high over the bar from distance, with Spurs moving with noticeably more urgency at the start of this second half. It’s a low bar, to be fair.

48 mins: Sessegnon whips a cross into Preston’s penalty area from the left but fails to pick a team-mate. Its delivery is cleared at the first post.

47 mins: Spurs advance and Dejan Kulusevski has a blocked shot after cutting in from the right.

46 mins: Play resumes with Spurs kick off and there are no changes in personnel on either side.

An email: “Only God knows how badly Emerson Royal would have been if he replicated what Sessengon is doing right now and what he has been doing this whole season,” writes Yash Gupta. “He gets the ball in nice areas and just throws it back to the opposition while his defense makes TAA a world class defender.”

Peep! A seriously disappointing first half is put out of its misery by referee Peter Bankes, but Preston manager Ryan Lowe won’t mind the scarcity of entertainment. His side defended well and limited Tottenham to three shots from range, but didn’t offer much going forward. Spurs looked clueless against a solid wall of white resistance.

44 mins: Now Sessegnon attempts to cross the ball near the left touchline, only to have his effort intercepted by Alan Browne. Moments before, Liam Lindsay had stretched a leg to prevent Kulusevski from shooting on goal with a nice block.

40 mins: From inside left space, Ryan Sessegnon tries to cross the ball towards the far post but sends it over the bar and onto the roof of the net, prompting whistles of derision from the Preston fans. It’s atrocious.

38 mins: Rodrigo Bentancur knocks the ball out of play following a dishonest touch. A free-kick for Preston, whose manager Ryan Lowe will be extremely pleased with his side’s defensive performance so far.

37 mins: From this corner, Spurs win another and the ball breaks towards Dejan Kulusevski. He shoots over the bar from a distance.

36 mins: Spurs win a free-kick wide on the right, deep into Preston territory, lined up with the front edge of the penalty area. Son’s delivery fails to clear Robbie Brady, the only man standing in front of him and the ball flies back over the Irishman and out for a corner. I’ve said it before and I’ll say it again, Son’s dead ball delivery is seriously questionable.

34 mins: A more solid and disciplined defense from Preston prevents Spurs from finding a way through their defence. Other than two long-range efforts from Son, they created nothing in this half.

33 mins: With all the time in the world at his disposal, Clement Lenglet massively overruns a pass to Son and sends the ball in for a goal kick. Can we have more balls on the pitch please?
