Harry Maguire's header and Andre Onana's stoppage-time penalty save secured Manchester United a vital Champions League win against Copenhagen in their first home match since the death of Sir Bobby Charlton.
Tuesday's Old Trafford encounter allowed the club to come together and pay tribute to the World Cup winner and all-round gentleman following his death at the age of 86 on Saturday.
Charlton starred for United and in 1968 led them to European Cup glory at Wembley, where Erik ten Hag's men would love to return for June's Champions League final.
First comes qualification from Group C, which misfiring United continued to make hard work of as they rode their luck to claim a 1-0 win against Copenhagen after losses to Bayern Munich and Galatasaray.
Maguire temporarily quietened his doubters with a second-half header against the impressive Danish champions, who pushed until the end and looked set to act as party poopers.
Scott McTominay brought down Mohamed Elyounoussi in the box in stoppage time, but goalkeeper Onana - so unsteady since joining from Inter Milan - saved Jordan Larsson's penalty in a jaw-dropping ending.
