Philippe Coutinho's moment of brilliance extinguished Manchester United's faint hopes and saw Liverpool through to the Europa League quarter-finals.
Boasting a two-goal advantage from last week's frenetic, one-sided encounter at Anfield, Jurgen Klopp's men made the short journey knowing an away goal at Old Trafford would throw their rivals' comeback hopes off-kilter.
For a while Louis van Gaal's side had looked capable of a memorable comeback, only for Coutinho's magic to kill the mood - and United's hopes of progressing from the last-16 tie - as Liverpool held out for a 1-1 draw on the night, seeing them through 3-1 winners on aggregate.
