- Monaco edge Dortmund in thrilling first-leg tie
- Mbappe scores twice - the second with stunning finish
- Dembele and then Kagawa hit back to give Dortmund hope
- Monaco missed a penalty early in the first half
Thomas Tuchel hugs all of his players and they acknowledge the terrific support as ever.
That was cracking stuff. I could watch Monaco every week I think.
Great game. After a tough 24 hours Dortmund really showed what they are made of in that second half.
Game very much on if you ask me.
Peter Malath: This Kylian Mbappe kid can be unplayable at times. How does Monaco keep producing this speedy kids? BLISTERING PACE
Josh Earl: well this game has been well worth the wait, two brilliant teams.to watch, football as it should be. Terrific from Kagawa
Was that the final glimpse of goal for Dortmund tonight?
Three minutes added on. CHANCE!
Ousmane Dembele whips it in, a header for Pierre-Emerick Aubameyang inside the six-yard box but Kamil Glik does enough to put him off and force the header over!
What's the price tag on Kylian Mbappe?
Thomas Tuchel is having kittens down there. Manic but with a smile emblazoned on his face as he throws men forwards. Don't lose the tie chasing an equaliser TT!
What a game we've had in the end. A 2-0 win in Monaco would do it for Dortmund next week but let's be honest, there's no chance that either side are keeping a clean sheet.
The game has delivered for the neutral, no doubt about that. Just as the Yellow Wall was falling silent, a ball in from the right is taken down by Shinji Kagawa, a great first touch, he then turns inside Jemerson with a second great touch, and slots home left footed!
Kylian Mbappe has now scored four goals in the knockout stage, that's a record for a teenager.
Bojan and Patrick Kluivert had two.
It's all gone quiet over there, you might say. Dortmund fans will know that their team can score anywhere but they need at least three in Monaco next week now...
Is that the goal that sends Monaco into the last four?
Yes, it comes from a defensive mistake but ladies and gentlemen, please, let's give the floor to this teenager. A finish which will give Monaco fans of a certain age memories of Thierry Henry or David Trezeguet.
A loose pass across from Lukasz Piszczek is intercepted by Kylian Mbappe, he's clean through on goal but still has work to do. Is he fazed?
Nope. Takes a touch and then laces the ball into the top corner from 22 yards. Outstanding.
Keep on pushing, keep on pushing...
GOT TO BE!!
Dortmund keeper Roman Burki has had nothing to do all half and goes to pieces, straying wildly off his line as Thomas Lemar's pass finds Radamel Falcao on the edge of the area.
Falcao's touch is vintage, his finish is village. Over the bar with an open goal.
The Falcao of Old Trafford...
On second viewing I'd probably agree. It was an inspired touch!
Sokratis Papastathopoluos is a bit lucky not to see a second yellow for a trip on Kylian Mbappe. His first foray of the second period.
Andy MJ: He 100% meant that pass, great skill from Aubameyang and a quality goal from Dortmund
So much pace! Ousmane Dembele breezes past Andrea Raggi, who then has the horror of seeing Christian Pulisic on the underlap. Help the man out!
Dembele swaps passes with Pulisic and then sees a shot deflected up and away for a corner. Surely a Dortmund leveller is on the way?
Dortmund's front three or four are linking up every time now. one, two-touch stuff. Monaco can't get out.
Nabil Dirar's first action is to be booked for shoving Shinji Kagawa. Harsh booking but another testing moment for the Monaco defence. Send the big men up..
Great ball in and well cleared!
Good free-kick whipped in by Dortmund but Joao Moutinho is able to scramble it clear. Christian Pulisic gets clear again on the right, he's been brilliant since coming on, and Monaco have to clear from inside their six-yard box.
A shame to see Bernardo Silva coming off but he's been a passenger in the second half. A night for engineers, not artists for Monaco now.
Silva off, Nabil Dirar on.
We expected goals Thomas, and we have them. Dortmund have had 71% of the ball since half time. Monaco can't get near it.
Thomas H: This is more like it from Dortmund. Direct attacking football. This game could turn into a goalfest over the 2 legs
What a ball that is! Raphael Guerriero puts in a hell of a cross with the outside of his boot, Roberto Carlos-like, it flashes through the goalmouth and is crying out for a touch!
We've got a game on now. Every bit as exciting as we hoped as both teams pile men forwards. It's been all Dortmund since the break to be honest. They deserved that goal.
For the second time tonight we ask whether a player meant that or not?!
A cross from the left is met by Pierre-Emerick Aubameyang, who is facing away from goal and falling to the ground but still somehow backheels a cushioned volleyed pass into the run of Shinji Kagawa. I don't think he can possibly have meant to...
It was brilliant if he did. Kagawa is in on goal, squares it and it's a tap in for Ousmane Dembele!
A much better 10 minutes for Borussia Dortmund. If they can end the night one goal behind they'll fancy their chances in the second leg won't they?
I say that, Thomas Tuchel is now going nuts in his technical area.
Lovely touch from sub Christian Pulisic, who I've just found out played for Northants side Brackley Town as a kid, he breaks into the area and slides a pass across but there's nobody there.
Pulisic then skins his man again but Ousmane Dembele's shot is blocked. Great impact from the American.
Monaco's Jemerson was shown a yellow card when giving away that free-kick a moment ago.
Dortmund win a corner now and Pierre-Emerick Aubameyang whips up the Yellow Wall who are in fine voice as ever.
Ousmane Dembele is probably the third or fourth best Dembele I've seen this season. We all dream of a team of Dembeles...
Dortmund starting brightly.
Close! Actually it's a way wide as Ousmane Dembele bends the free-kick over the wall and almost into the head of the official behind the goal.
Dortmund have kept with three at the back but put Raphael Guerreiro at left wing-back now.
Straight from kick-off Dortmund almost slice through the middle but Pierre-Emerick Aubameyang is fouled on the edge of the area!
Here we go then - the teams are out and Dortmund make a double sub.
Youngster Christian Pulisic and Nuri Sahin come on, Sven Bender and Marcel Schmelzer are off.
Monaco have conceded 13 goals in the Champions League this season – including eight in their last two away games – more than any other team among the remaining quarter-finalists.
Monaco also missed a penalty in the first leg of their tie with Manchester City in the last round. They got away with it on that occasion - will they this time?
