Full-time: Tottenham 0-1 Bayer Leverkusen
All over and Spurs can have no complaints. Mauricio Pochettino's men were second best and are now facing a real fight to qualify for the next round.
Until next time, folks...
Five minutes added. Still time for Spurs to find an equaliser.
It's 0-0 in Copenhagen, while another Spurs attack has come to nothing - and time is running out in both games.
Spurs are starting to find a little bit of momentum here. On this occasion, Ben Davies goes on an adventurous run forwards, but his strike goes just the wrong side of the post from his viewpoint.
Eric Dier - who has had a terrible evening, to be frank - smashes a free-kick against the bar!
The goalkeeper was beaten and the rebound was cleared from danger when Janssen seemed certain to poke the ball home.
A decent number of fans are already leaving Wembley, by the way. Seems a bit premature to me.
Spurs insist on trying to play their way out of defence, but they're getting themselves in a right old muddle. So many of their problems have been self-inflicted this evening.
Son is replaced by N'Koudou. That's the last of Spurs' three changes and unless things change, they are looking at another bleak night at Wembley.
I've got to say, they have fallen woefully short of their own standards this evening. And it appears the pressure of Champions League football has got to this young, but inexperienced side.
The crowd are starting to voice their frustrations, too.
Spurs' response is immediate. Harry Winks comes on for Eriksen.
Brandt off, Calhanoglu on for Bayer.
GOAL: Tottenham 0-1 Bayer Leverkusen
The Germans hit the front at Wembley!
A series of one-touch passes on the edge of the box end with a right-footed shot from distance that deflects into the path of Kampl, who slots in from close range.
Kyle Walker has had enough of this, clearly, and so he goes flying up the right side, beating one, two, three defenders before firing his shots just wide of the upright. It's getting better bit by bit for Spurs.
Having said that, Eric Dier misplaces a pass and is lucky that Hernandez is not able to find a way past Lloris, who gets to the ball on the second attempt.
Spurs launch a quick counter, going from one end of the field to the other - but the move ends with Janssen failing to wriggle clear of his marker and his scuffed shot sails over the bar.
A reminder of who is on the Spurs bench: Vorm, Carter-Vickers, Rose, Winks, Onomah, Nkoudou
Do they have a game-changer in their ranks?
The Spurs fans are trying to get their team going and to their credit, the Londoners have started on the front foot. I imagine there were a few stern words said at the interval.
Ah, we've already had more action in the first two minutes of this half than in the entirety of the first! Dele Alli dribbles into the box and goes down under pressure. A penalty for Spurs? No, the ref is not interested.
Moments later, Eriksen's low, right-footed effort drifts agonisingly past the far post. That was MUCH, MUCH better, though.
Back under way at Wembley. There are a whopping 85,512 people inside the stadium tonight, by the way.
Half-time: Tottenham 0-0 Bayer Leverkusen
It can only get better in the second half. That's the best way to look at it. Back for more soon.
The Champions League is Europe's premier club competition - but this game hasn't matched that billing so far.
And yet as I say that, Kyle Walker gives the ball away on the edge of his own box, before Javier Hernandez's goal-bound effort is deflected wide of the post. That's as close was we've come to a goal.
Not a great half of football, this. I wonder whether Maurcio Pochettino is already considering another shake-up at the break.
How did the Dembele change alter Spurs' shape? Well, from what I can tell, Son has moved to the left and Eriksen into the centre, with Janssen playing up top. That all means Dele Alli has moved a little deeper.
Tottenham are currently in the midst of their best spell of the half, although that's hardly a bold statement.
Eriksen gives the crowd something to cheer, making a break through the centre before smashing his effort straight at the goalkeeper. The first real sign of encouragement from Spurs, that.
Monaco have gone two goals up against CSKA Moscow in Spurs' group. Remember, the Ligue 1 side beat the Londoners at Wembley earlier this season.
Dembele has picked up and injury and Spurs need to make a change. It looks like Vincent Janssen will be the man coming on, which is likely to mean Alli or Eriksen will have to switch position.
Dembele commits a professional foul and is lucky to escape a booking. There are already a few groans audible around Wembley, suggesting the Spurs fans are not especially impressed by what they're seeing.
The north London side have not found any fluency so far and are giving the ball away all too easily.
