United entered the final 20 minutes with a two-goal lead on the night and on aggregate, and looked to be on the way to securing a comfortable passage to the UEFA Europa League semi-finals, before a spirited Lyon comeback sparked an ending of epic proportions in M16.
Our French visitors scored twice to level the quarter-final tie and, with a man less following Corentin Tolisso's 89th-minute red card, netted two more in extra-time to leave Ruben Amorim's Reds staring down the barrel of a sudden exit.
An unimaginable turnaround was needed to swing things back in our favour but three goals in seven glorious minutes followed, first Bruno Fernandes from the penalty spot, then a cool curling finish from Kobbie Mainoo before an added-time winner off the forehead of Harry Maguire that sparked utter euphoria.
