Midtjylland, who haven't played a competitive game in two months, are in control of this tie. A truly abysmal performance from United that ranks alongside the one away to Olympiakos under David Moyes in 2014 as their worst in recent memory.
FULL TIME: Midtjylland vs Manchester United
Sisto pings a poor effort into the wall and Pereira breaks forward with promise. Pity we are out of time.
Midtjylland have a free kick just outside the box as Smalling holds back Ureña. Yellow card for the United centre half, and this free kick should be the last chance of the game.
The corner is met by Carrick, but his header is a poor one and the balls sails over. Four minutes of time added on.
United venture foward now with Pereira trying to jink his way into a shooting position but can't find one. He plays it wide to McNair who wins a corner.
Less than five minutes remaining here, United look to have no interest in scoring. The dismal performance is summed up again as Herrera pings a pass out to Lingard whose attempt to control it is hopeless.
Midtjylland showboating now, United offering absolutely nothing.
Mata was hauled off just after that goal, by the way, replaced by Andreas Pereira.
More laughs from United as Smalling and Romero can't make up their mind who is claiming a through ball, allowing Kadlec in to drag a shot just wide of the target.
Oh Juan. An absolutely pitiful attempt from Mata to try and win the ball from Onuachu on the edge of the box is the latest in a string of embarrassing moments for Louis van Gaal's side. The substitute steps away from the Spaniard easily and arrows a fine effort into the bottom corner.
Goal! Midtjylland 2-1 Manchester United (Onuachu)
15 minutes to go in this game and Midtjylland are the side looking the far more dangerous at the moment.
Schneiderlin, just off the bench, tries to hook a ball into the box but it is charged down by Kadlec, who keeps the Frenchman under pressure and wins the ball too easily to spring forward. They just about recover the ball but United are offering absolutely no protection to their defence at the minute, each time Midtjylland come forward they do so almost unchallenged.
Hansen plays a ball forward for Kadlec who tries for goal from 20 yards out, but it's wide. Carrick and Herrera might as well not be out there, Midtjylland are strolling through midfield with ease on each occasion.
United almost caught out as Herrera - who has having a dreadful game - loses the ball on the half way line, allowing Onuachu to race forward. He plays it wide to Ureña who threads a pass across for Sisto, who again cuts in onto his right and tries to curl one towards the far corner, but his radar is off this time.
United are 20 passes in to a move when Love tries to thread a precise one through down the inside right but goalkeeper Andersen is always the favourite to reach it first.
Sergio Romero saves United again! Just off the bench, Onuachu meets a wonderful cross from the right with a header that seems destined for the top corner, only to see the Argentine goalkeeper spring across goal and claw it out. The ball breaks loose momentarily, but Romero is alive to it and follows up his terrific first save by batting the ball clear to safety.
United have dominated the last 10 minutes or so; in that time they've hit the bar and had two very decent chances to go back ahead.
Another neat move sees Love drive forward, finding Memphis who lays an inviting one off for Herrera to run onto. It's from a tough angle, but you would expect the Spaniard to hit the target. He doesn't. Not even near. Miles away.
Lingard hits the bar! Memphis pings an outside-of-the-boot out to Herrera who dinks in a wonderful ball that Lingard meets with a volley. It's a decent connection, unlike his last few efforts, but he can't keep it down and it cracks off the woodwork.
Great chance for Mata as Memphis picks him out at the near post but the Spain international plants his free header to wrong side of the post. Another really poor effort.
Herrera loses the ball again inside his own half, allowing the home side to pick out their dangerman Sisto. He cuts in onto his right foot menacingly again but this time his vicious shot his straight at Romero.
