David de Gea thwarted Sevilla in the first leg and made several good stops at Old Trafford too, but Wissam Ben Yedder came off the bench to score the goals that earned Sevilla the victory over Manchester United that their play over 180 minutes deserved.
Marcus Rashford and Marouane Fellani both looked lively when going forward for the home side in the first half, but Sevilla were generally comfortable and frequently arrived in the final third with purpose too.
The start of the second half was very end to end and both teams looked capable of scoring, while at the same time this second leg also strangely felt as if it could finish 0-0 too, so good were the goalkeepers and so poor was the finishing.
In the 72nd minute Vicenzo Montella rolled the dice and took off his favoured centre-forward Luis Muriel to give Ben Yedder a chance and the Frenchman immediately showed his coach what he is capable of.
He collected the a neat pass from Pablo Sarabia and put the ball in the bottom corner, out of De Gea's reach.
Jose Mourinho made a double change in response, but before United could settle Ben Yedder had scored again, with De Gea unable to keep the striker's far-post effort from sneaking over the line.
Romelu Lukaku did pull one back for United with six minutes to go, but the best chance of the remaining few moments actually fell to Ben Yedder, who was denied a hat-trick by the foot of De Gea.
He won't care too much, though, as he became the man who put Sevilla in their first quarter-final since 1957/58, in the process becoming a legend of the red and white half of the Andalusian capital.
