It may not have been Manchester United at their vintage best but a heroic late show from Andre Onana ensured their Champions League campaign is finally underway.
United looked to be eeking out a narrow 1-0 win at Old Trafford thanks to Harry Maguire's goal.
But when Scott McTominay conceded a penalty in the fifth minute of stoppage time, a familiar sense of dread crept in, with United having lost their opening two group games and they were now staring more dropped points in the face.
Onana, who has been widely panned for his displays in this competition this season, backed himself and pulled off a stunning penalty save with the last act of the match.
