Denmark looked to try to move themselves back into World Cup qualifying contention in Group B when they hosted Armenia in Copenhagen.
The Danes were fourth in the group with six points from five matches, but had played a game less than those above them.
Armenia had lost all bar one of their group fixtures, after they earned a victory over Malta in their opening match of qualifying.
However, Denmark endured a shock thrashing at the hands of an impressive Armenia side.
Read how the action unfolded in our live commentary below.
Good evening, and welcome to Sports Mole's live coverage from Copenhagen, where Denmark host Armenia.
Tonight's clash is a big match for both sides in Group B of the World Cup qualifiers. Denmark can move to joint third and a point behind second place with a victory, while a win for the Armenians will move them clear of the bottom spot.
Two teams can progress to Brazil from this group. The automatic top spot looks likely to be taken by Italy, who are still unbeaten and four points ahead of Bulgaria in second. The country who finishes second will also have a shot at earning a flight to South America, but only after they have played a playoff tie against another runner-up.
Denmark go into this match having drawn their last outing with Bulgaria, which came after beating third-place Czech Republic. Armenia, however, have lost their last three qualifying matches, including a 1-0 defeat to basement side Malta last week.
The team news is in...
DENMARK XI: Andersen, Zimling, Kjaer, Bjelland, Poulsen, Jacobsen, Kvist, Eriksen, Krohn-Dehli, Rommedahl, Cornelius
So the familiar names you will probably recognise from the Danes starting lineup would be Ajax's Christian Eriksen, who is one of the most sought-after talents in European football at the moment, as well as former Charlton Athletic speedster Dennis Rommedahl.
Right, let's see who lines up for Armenia tonight.
ARMENIA XI: Berezovski, Haroyan, Arzumanyan, Mkrtchyan, Edigaryan, Ghazaryan, Hovhannisyan, Movsisyan, Aleksanyan, Mkhitaryan, Ozbiliz
I'll pass on the names that you will recognise from that lot.
The two sides are out and are exchanging national anthems. Armenia have done theirs, so now it is Denmark's turn.
There is no Daniel Agger or Nicklas Bendtner for the Danes tonight who are both injured, but Leicester City's Kasper Schmeichel is on the bench.
The pressure is no doubt on the Danes tonight, with the home crowd expecting a win.
WE'RE OFF!
GOAL! Denmark 0-1 Armenia (Yura Movsisyan)
Wow! I wasn't expecting that. Just 25 seconds into the match, and Armenia are in front. The ball was terribly given away by Poulsen, and Movsisyan was played in on the left of the box before half-volleying past Andersen. What a shock!
CHANCE! Denmark nearly have an instant equaliser as Rommedahl bombs onto a through ball on the right of the box. The keeper Berezovski comes to meet him, and the winger chips it over his head. However, it is cleared off the line by a retreating defender.
YELLOW CARD! Controversial moment here as the referee Aleksei Nikolaev has adjudged Krohn-Dehli to have dived after a clash with a defender. He then puts the forward into the book. It was a close one, but Krohn-Dehli made too much of a meal about the challenge.
Rommedahl completely loses his marker again as he runs in from the right to meet the ball on the penalty spot. It's a brilliant opportunity for him, but his control is awful and the ball runs out of play.
Denmark have been on top since going a goal down early on, but they have been sloppy so far.
Great defending from Arzumanyan, who shields the ball from Eriksen in the corner to win a goal kick.
CHANCE! How has Dennis Rommedahl not scored yet? That's the third chance he has had, and with finishing like that you can tell why he hasn't scored an international goal in nearly two years. He is played in on the left side of the box and just has the keeper to beat. He should be rolling this ball into the bottom right corner, but instead he drags it miles wide.
CHANCE! My word Armenia are fractions away from doubling their lead. The ball is played in from low the right, and Simon Kjaer makes contact with his shin. The ball then spurs up and into the sidenetting for an Armenia corner. Massive let off there for Kjaer.
OFF THE POST! Armenia again come very close against a very ordinary Denmark defence. It's Movsisyan who takes the shot on from the edge of the box and it flies towards the bottom corner. Andersen flings himself to his right, and touches the ball onto the post before Jacobsen can hack the ball clear. This is unreal.
GOAL! Denmark 0-2 Armenia (Ara Ozbilliz)
What an earth is going on? Armenia have now doubled their lead and it is once again another terrible display of defending from the Danes. Kjaer is guilty once more of playing his marker onside, and Ozbilliz fires an effort past Andersen and into the back of the net.
Denmark could be watching their hopes of a place in Brazil slipping away.
Rommedahl is the target again once more with his lightning pace, but this time he is flagged offside.
Morten Olsen, the Denmark boss, looks like he may make a couple of early changes. The substitutes are vigorously warming up.
Denmark have a chance from the corner, but the delivery fails to beat the first man, who headers it away.
And they are about to make a change, Nicklas Pedersen is kitted out and ready to come on.
DENMARK CHANGE Pedersen comes on in place of defensive midfielder Niki Zimling. Bold move that has been forced on Denmark to bring on the forward.
CHANCE! Denmark are presented with another chance and it falls to the substitute Pedersen. He comes into this strike at such a weird angle, almost running away from goal, and swings a boot on the turn only for the shot to curve wide.
Armenia have bodies behind the ball at the moment as they manage to clear away another dangerous cross. Denmark need to speed up the tempo and make the most of these decent positions they are getting into.
YELLOW CARD Varazdat Haroyan goes into the book for a challenge that didn't even look as if he touched Jacobsen.
CHANCE! Simon Kjaer, who was at fault for both goals, nearly pulls one back for Denmark when he meets the free kick at the far post, but his header bounces wide across the face of goal.
CHANCE! A ruckus has just unfolded in the Denmark penalty area. Initially it is wonderful approach play from the Armenians, and Ozbiliz founds himself one-on-one with Andersen. However, the keeper makes himself big and meets the ball in mid-air. Denmark can then hack away the danger.
Without Agger, Denmark are a shambles at the back.
Pedersen gets a telling off after yanking down Aleksanyan in the corner. Pure frustration being shown by the Danes here.
YELLOW CARD Robert Arzumanyan is given a yellow for wasting time.
CHANCE! This is crazy. Despite leading, Armenia look the side more likely to score next. Movsisyan plays a lovely pass through to Aleksanyan, who takes on his marker but fires a shot over the bar with his left boot from just inside the box.
Two minutes of added time to come.
Denmark have a free kick 30 yards out. Eriksen step forward.
That's into the wall, and that sums up Denmark.
HALF TIME: Denmark 0-2 Armenia
Wow, who would have thought that. Denmark have been awful, Rommedahl wasteful and Movsisyan and Orbiliz have given Armenia a 2-0 lead at the break. They deserve it.
We're just moments away from the second half, and boy do Denmark have work to do.
Denmark have made their way up the steps and are now back on the field.
Are Armenia shortly follow.
Denmark have made a change at the break and taken off Andreas Bjelland and brought on Jores Okore.
WE'RE BACK UNDERWAY IN COPENHAGEN
Denmark are now playing a 4-1-3-2 formation following that change.
CHANCE! Kjaer rises up to meet a long throw, and he forces a decent save from Berezovski.
Denmark already look better in this second half. Seem more fluid and have more room to attack in the final third.
Half a chance for Cornelius, who then throws himself to the ground under a challenge in the box. But nothing is given.
CHANCE! Cornelius shows brilliant control to take Kjaer's header on the chest before overhead kicking the ball over the ball marginally. The move started from a Kvist long throw, which they seem to be favouring.
Nicklas Pedersen, who only came on in the 28th minute, is signalling that he has to come off.
DENMARK CHANGE Off comes Pedersen then with the help of the physio, and Simon Makienok makes his fourth appearance for the Danes.
CHANCE! Ozbiliz has a crack on goal from the edge of the box with a very wobbly effort. Andersen can palm the ball away though.
Ozbiliz has a half-chance as the ball is free on the left, but his shot is pretty much a pass back to Andersen.
Armenia are still comfortable here. Denmark need a goal badly.
CHANCE! Great opportunity for the Danes, as the ball drops to Okore, who tries to hit the ball on the turn, but his shot is well saved.
GOAL! Denmark 0-3 Armenia (Yura Movsisyan)
This is unreal, Armenia have a third and what a good finish this is from Movsisyan. He is poked through on the left of the box, and from a very acute angle, he guides the ball into the far corner. Brilliant finish.
Denmark have a free kick literally right on the edge of the box. It's almost too close for them, as Eriksen slams the ball into the wall. Armenia can break, and Movsisyan hammers a ball towards the far corner, but there is a great block in there.
Jacobsen wastes a good chance for Denmark, who has two players free at the back post, and chips the ball out for a goal kick. Poor.
20 minutes to go, and this looks like as if it is all over. Denmark struggling, Armenia comfortable.
CHANCE! It is very nearly four! Andersen makes a great save at first to deny Movsisyan, before Kvist denies the second effort with a block on the line.
Ghazaryan hobbles off the field temporarily after a clash with Rommedahl. The Dane fouled him initially before what looked like a rake down the Armenian's leg. Naughty.
OFF THE POST! Denmark come close and strike the frame of the goal following a deflected shot from Makienok.
CHANCE! It's another great chance for Makienok but he is brilliantly stopped at close range by Berezovski following a deflected free kick that fell at the feet of the forward.
GOAL! Denmark 0-4 Armenia (Henrikh Mkhitaryan)
This is humiliating for Denmark, it's unbelievable! Danish fans applaud Shakhtar forward Herikh Mkhitaryan for this. He holds the ball up after good play down the right, and waits for the distraction from the onrushing defender. The chance opens up, and he slams the ball in the corner. That's why Liverpool are rumoured to be interested in him.
ARMENIA CHANGES Sarkisov and Pizzelli comes on for Movsisya Edigaryan.
Three minutes to go here.
ARMENIA CHANGE Sargis Adamyan comes on as Denmark fans provide Ozbiliz with a standing ovation as he leaves the field.
FULL TIME: Denmark 0-4 Armenia
Wow what a shock, Denmark are stunned in their own back yard. Armenia equal their-biggest ever win, and surely their best-ever win.
Denmark were awful, Armenia were class and the two sides are now level on six points in Group B.
That's all from me. Good luck getting your head around that result. Until next time, goodbye.
