We've ticked into the first of two minutes of added time. Tottenham are just about ready to celebrate a job well done.
86'
Kane puts the ball in the net for the second time, but the flag had long been hoisted. There might be a second goal on the counter for Tottenham if they're hungry enough.
84'
Bruun Larsen's hopeful shot deflects off Gotze and straight into Lloris' hands.
83'
D. Rose enters the game and replaces C. Eriksen.
Rose is introduced for the final seven minutes of normal time, relieving Eriksen in midfield.
82'
They arrived in Germany in ordinary form but this has been a second-leg masterclass from Spurs. Pochettino's team withstood a heap of early pressure, struck early in the second half and are now cruising towards a big aggregate victory.
79'
Just over 10 minutes remain at Signal Iduna Park and Tottenham are firmly on course for their first appearance in the Champions League quarter-finals since 2011.
76'
Delaney delivers from deep and Pulisic, left unmarked in the box, balloons the header over the bar.
74'
T. Delaney enters the game and replaces M. Reus.
This change might suggest that Favre knows the tie is over. Reus is off and midfielder Delaney comes on.
73'
With five clearances, three tackles and three interceptions, Vertonghen is mounting a convincing case to be named man of the match. His early challenge on Reus set the tone.

Description
71'
É. Lamela enters the game and replaces Son Heung-Min.
Son's night has come to an end with Lamela introduced for the final 20 minutes. Tottenham continue to lead 4-0 on aggregate.
69'
Sissoko leads a positive surge forward and slips the ball into Son. The shot is deflected out for a corner, which Alderweireld nods over.
67'
Dortmund are moving the ball around without a whole lot of intent or direction. Every player bar Kane is defending for Tottenham.
62'
J. Bruun Larsen enters the game and replaces M. Wolf.
C. Pulišić enters the game and replaces Raphaël Guerreiro.
Favre seeks to reinvigorate a clearly dispirited Dortmund. Pulisic is on first in place of Guerreiro.
The double change also sees Bruun Larsen enter the fray in place of right-back Wolf.
61'
The hosts are patiently working the ball around without much success. Wolf's crossing in particular has been a letdown for Dortmund.
58'
Kane's strike against the run of play seems to have completely taken the air out of Dortmund. They have to score a highly improbable five goals to get ahead on aggregate.
55'
E. Dier enters the game and replaces H. Winks.
Pochettino won't be pleased to have lost Winks but he has a solid replacement available in the fit-again Dier. The midfielder has missed the past six matches due to tonsilitis.
50'
Kane's full of confidence now! He sees Burki a long way off his line and looks to chip the goalkeeper from way out, but the effort drifts comfortably over the bar.
48'
H. Kane has scored a goal for Tottenham Hotspur! Assist by M. Sissoko.
He barely saw the ball in the first half but that was clever from Sissoko to release Kane first time after Eriksen's pass deflected into his path.
GOALLL!!! Kane pounces and Spurs are surely headed for the quarter-finals! Dortmund are caught napping at the back as Sissoko plays Kane in for a one-on-one, and the striker makes no mistake with a cool finish inside the near post. 1-0.
46'
Back underway at Signal Iduna Park, where Dortmund have 45 minutes to erase a three-goal deficit against Tottenham.
It's a quick return to type as Alcacer deftly releases Reus in behind, with the captain's attempted cross flashing across the face of goal.
45' +3
HALF-TIME: BORUSSIA DORTMUND 0-0 TOTTENHAM
45' +1
An Eriksen corner is easily dealt with by Reus as the half-time whistle approaches.
44'
Lloris reads Alcacer's curling finish and gets across to his left to hold the attempt. Spurs' skipper is proving his worth in these opening 45 minutes.
43'
Not long left in the first half and it remains goalless in Dortmund.
39'
Pochettino's men have just managed to calm things down in the last couple of minutes. It's been a gritty, backs-to-the-wall showing, with blocks, saves and last-ditch tackles needed to deny Dortmund.
37'
Tottenham are under real pressure. They did well to survive moments ago and will be fortunate to reach the interval unscathed. Sancho is the latest Dortmund player to try his luck, shooting straight at Lloris.
28'
Wolf, found overlapping on the right by Sancho, delivers a low cross that's far too close to Lloris. Almost half an hour gone in Dortmund.
26'
We've passed the 25-minute mark and Dortmund's dominance is yet to pay dividends on the scoreboard. As it stands, Spurs are still firmly in the driving seat.
24'
Dortmund are queuing up at the moment! Diallo has time and space on the left to pick his pass, which he uses to find Gotze at the top of the box. The shot, though, is struck straight into a Tottenham defender.
20'
There was plenty of pre-match talk about the need for Tottenham to survive the opening 20 minutes without conceding. Well, they've just about ticked that box.
18'
Tottenham have given the ball away in their own half on multiple occasions thus far. It's a risky tactic defending so deep, but Dortmund will have to be clever to find a way through.
17'
Alcacer takes down a lofted Akanji pass, holds off Sanchez and then pokes over the crossbar, but the flag is up anyway.
14'
Reus looked destined to score with that last chance after Sanchez made a hash of a ball over the top. This is going to be a nervy 90 minutes for Pochettino.
11'
Excellent tackle from Vertonghen! That was crucial. The Belgium international times his sliding challenge perfectly to hook the ball away from Reus.
9'
Tottenham certainly look to be employing a back five when out of possession with Aurier and Davies dropping deep.
7'
Reus gets a head to Guerreiro's dinked ball into the box, but it runs away from Alcacer and Lloris cleans up. Dortmund now enjoying the better of possession.
6'
Tottenham navigate a couple of testing moments as Sissoko heads away a corner before Vertonghen clears Sancho's low ball in from the right.
4'
Sancho threatens to get away down the right but Sanchez shows a good turn of pace to come across and win the ball.
2'
Tottenham are looking to get their foot on the ball in these early exchanges. They'll want to take the sting out of a boisterous atmosphere.
1'
We're underway at Signal Iduna Park! Dortmund have a three-goal deficit to make up.
Hello and welcome to our live coverage of this Champions League clash between Borussia Dortmund and Tottenham!
Tottenham take a commanding advantage into the return leg of this last-16 tie after recording a 3-0 victory when the teams met at Wembley last month. Son Heung-min, Jan Vertonghen and Fernando Llorente were all on target in a dominant second 45 minutes as Spurs secured the joint-largest Champions League win in their history. Recent weeks have been less rosy, though, with Premier League losses to Burnley and Chelsea followed by a fortuitous draw against Arsenal in the north London derby, and they will want to start well in Germany.
Dortmund find themselves in a similar rut at a poor time of a campaign that promised plenty not so long ago. Lucien Favre's men have won one of seven matches in all competitions since the start of February, with their comfortable buffer over Bayern Munich in the Bundesliga reduced to nothing more than goal difference. They lost 2-1 at Augsburg on Friday and are in desperate need of a morale boost, perhaps beginning here at Signal Iduna Park.
BORUSSIA DORTMUND SUBS: Marwin Hitz, Achraf Hakimi, Marcel Schmelzer, Dan-Axel Zagadou, Thomas Delaney, Jacob Bruun Larsen, Christian Pulisic.
TOTTENHAM XI (3-4-1-2): Hugo Lloris; Toby Alderweireld, Davinson Sanchez, Jan Vertonghen; Serge Aurier, Harry Winks, Moussa Sissoko, Ben Davies; Harry Kane, Son Heung-min.
TOTTENHAM SUBS: Paulo Gazzaniga, Danny Rose, Eric Dier, Victor Wanyama, Lucas Moura, Erik Lamela, Fernando Llorente.
The players are out on the pitch and we're just moments away from getting started!
BORUSSIA DORTMUND XI (4-1-4-1): Roman Burki; Marius Wolf, Julian Weigl, Manuel Akanji, Abdou Diallo; Axel Witsel; Jadon Sancho, Mario Gotze, Marco Reus, Raphael Guerreiro; Paco Alcacer.
If Dortmund are to find a way through, they're likely going to need a little extra from Alcacer and Sancho. The former has been restricted to 16 touches, while the young Englishman has generally been on the fringes in attack. Tottenham, though largely a non-factor going forward in the first half, will still fancy their chances of finding the goal on the break that would kill off this tie.
BVB finished above Atletico Madrid in Group A but their Champions League campaign has come to a disappointing conclusion. The 3-0 first-leg deficit ultimately proved well beyond a team that has lost its way in recent times. Favre will need to refocus his young squad on the fight for the Bundesliga title, which continues at home to Stuttgart on Saturday. Spurs, meanwhile, are sure to take a much-needed dose of confidence into the Premier League excursion to Southampton.
That concludes our live coverage of a memorable triumph for Tottenham. Until next time, it's goodbye for now.
