90' + 3' PEREIRA!!! IT'S 5-0! And it's an error from Schlager! Following a quickly taken free-kick, Pereira tries his luck from distance and hits the jackpot as the LASK goalkeeper can only help the ball over the line.
90' + 1' GREENWOOD MAKES IT 4-0!!! United hit LASK on the counter as Chong picks out Greenwood with a terrific pass. The forward darts into the area before drilling a low shot past Schlager at his near post.
82' MATA!!! 3-0 MANCHESTER UNITED! Fred demonstrates terrific vision before executing a wonderful through ball for the Spaniard, who sets himself before calmly slotting past Schlager.
58' JAMES MAKES IT 2-0!!! United double their lead as Ighalo feeds a neat through ball to the Wales international, who cuts inside before drilling a low shot into the bottom corner.
57' United continue to threaten. Ighalo lays the ball to the edge of the area for McTominay to strike, but his low side-footed effort is straight at Schlager.
56' Danger for the hosts as Shaw breaks with pace from the left flank and darts into the penalty area. However, the full-back is caught in two minds at the vital moment and the chance goes begging.
28' IGHALO!!! 1-0 MANCHESTER UNITED! What a finish! Good persistence sees the ball break kindly for Fernandes, who demonstrates good awareness to pick out Ighalo on the edge of the box. The Nigerian neatly juggles the ball to set himself, before firing a ferocious left-footed strike home off the underside of the crossbar.
26' James will be desperate to get back among the goals for United. The Wales international has gone 32 games without finding the net, although that is certainly no reflection on his overall contribution since making the move from Swansea City last June.
24' GOOD SAVE! Space opens for James to drill a low shot towards goal, but Schlager reacts quickly to push the effort away. From the resulting corner, McTominay heads wide of the target.
22' Schlager has been an ever-present between the sticks for LASK in this season's Europa League. Along with Wolves, the Austrian Bundesliga leaders are one of just two group-stage debutants still involved in the competition.
18' CHANCE! A terrific ball from Fernandes releases Shaw down the left. The full-back's cross is parried straight to Mata, whose shot deflects wide off the leg of Ranftl.
17' For all of United's success in Austria - winning on seven of their eight previous visits - it is worth noting that they have won just once in their last five away games in Europe. That is something LASK will look to use to their advantage here.
15' Today marks United's first trip to Austria in nearly 20 years. Their last venture to this part of the world brought a 2-0 victory over Sturm Graz in December 2000. Goals from Paul Scholes and Ryan Giggs decided the Champions League encounter.
13' Fresh from that wonder goal against Manchester City on Sunday, McTominay tries his luck from range again here. However, this time, his effort is way off-target.
12' United very much in charge after the opening 12 minutes at the Linzer Stadion. The visitors have enjoyed most of the possession and look dangerous going forward.
9' Eyebrows were raised when Ighalo arrived at Old Trafford on loan from Chinese Super League side Shanghai Shenhua in January. Nevertheless, the Nigerian has made a bright start to his United career with three goals in two starts.
7' Fernandes involved again as he seeks out Ighalo with a well-timed through ball. However, Schlager is quickly out of goal to clear the danger.
5' Fred has United's first shot of the game, but it is not the best in all fairness. The ball is laid off to him by Fernandes 25 yards from goal, but his strike is always rising.
3' Solskjaer's men arrive in today's first leg off the back of a 10-match unbeaten run in all competitions. Seven of those have been victories.
