United's Europa League campaign comes to an end. Liverpool have produced a thoroughly professional performance away from home to take the tie 3-1 on aggregate, having killed the game off with an equaliser on the stroke of half time.
Manchester 1-1 Liverpool
Liverpool win 3-1 on aggregate and progress to the quarter-finals of the Europa League
De Gea again denies Origi and Darmian manages to get to the loose ball just before Allen and clear.
Origi almost finishes United off after a driving run into the box but it is a relatively comfortable save for De Gea. United started very brightly in this game, but their second-half performance has been utterly toothless.
Ryan Giggs is patrolling the touchline, screaming instructions to his players.
The resulting corner pinballs around the United box with a few rubbish efforts on goal blocked until Lingard takes responsibility, lashing a powerful effort just wide of the post.
The Stretford End screams for a handball as Valencia's cross hits Milner's arms but the appeals are turned down.
Schweinsteiger lifts it in but it is cleared by the first man. Blind picks up the pieces and tires an ambitious effort of his own, but it's sent well wide. 85 minutes of this match remaining, United don't look like scoring in the next five hours, let alone the next five minutes.
Jesse Lingard embarks on a hopeful drive forward on his own and gets into the final third before Firmino hauls him down and the Brazilian is booked.
Coutinho takes it, but lifts it well over the bar.
Schweinsteiger is now booked for a dreadful challenge on Lallana right on the edge of the box.
Firmino pulls another fine save out of De Gea but the Brazilian was offside as he lashed his effort on goal.
And Coutinho almost did there, getting the ball on the edge of the box and lashing a vicious effort on goal, but De Gea again is equal to it.
United are done here, no fight, no drive, nothing. It's a matter of time before Liverpool finish them off.
Liverpool almost finish United off. Can bursts down the inside left and knocks it back through Darmian's legs with a deft back heel, straight into Coutinho's path. He takes a touch before shooting, but it is straight at De Gea.
Rashford does brilliantly, exchanging one-twos with Valencia down the right before cutting a fine ball back for Fellaini. All he has to do is keep his composure, but he sends his effort well over the bar. Dismal effort.
Last roll of the dice for van Gaal, a half-fit Bastian Schweinsteiger is coming on for Carrick. Divock Origi meanwhile is on for Sturridge.
Utterly bizarre from United and Fellaini. The Belgian gets the ball on the edge of the box and has the time and space to turn. Instead, he turns again and passes behind him.
United aren't quite pedestrian in possession at the minute, but with 25 minutes to go they need to speed it up. Carrick is robbed of the ball by Can on the edge of his own box but luckily for him, Blind is on hand to clean up.
Neat interplay involving Valencia, Martial and Lingard sees United create another half chance, with the latter backheeling a lovely ball into the Frenchman's path, but he smashes it clean over the bar.
Coutinho dances past three meek challenges from United players with an eye for goal, but instead slots it to Sturridge who fires a wild one into the crowd. Sublime stuff from the Brazilian.
United are having their share of half-chances, but they haven't forced Mignolet into a good save since Lingard's header in the first half. Liverpool are lying wait on the break.
Another big chance passes United by. Carrick swings in a beauty of a cross from deep that is telegraphed for Fellaini 's head, but his header is a tame one straight at Mignolet.
Another change for United, Matteo Darmain is coming on for Rojo. Both full-backs changed with United pursuing three goals.
