Roony Bardghji (17y 358d) was the youngest player to score against Manchester United in the Champions League, while he is only the second 17-year-old to score against an English side in the competition, after Jude Bellingham v Man City in April 2021.
Manchester United lost a Champions League match in which they led by two or more goals for the very first time. In all competitions, this was the Red Devils' first defeat after taking a two-goal lead since September 2014, when they lost a Premier League game 5-3 to Leicester City.
Among Premier League sides, only Burnley (10) have lost more games in all competitions than Manchester United (nine) this season. Nine defeats is the Red Devils' most in their opening 17 matches of a season since 1973-74 (also nine) under Tommy Docherty.
Rasmus Hojlund is Manchester United's top scorer in all competitions this season with five goals, with all five strikes coming in the Champions League. Hojlund has reached five goals in the competition in four appearances, the quickest any player has ever done so for the Red Devils.
Aged 20 years and 277 days, Rasmus Hojlund became the youngest player to score twice in an away Champions League match for Man Utd.
Mohamed Elyounoussi has two goals in four Champions League games for FC Copenhagen, as many as he scored in 11 appearances in the competition for Basel beforehand. He scored his first goal against Man Utd in his sixth appearance in all competitions against them.
Marcus Rashford was given only his second red card in 374 Manchester United appearances in all competitions, and first since September 2018 v Burnley.
Jonny Evans made his first Champions League appearance for Manchester United since December 2013 v Shakhtar, nine years and 333 days ago. The only player to have a longer gap between games played for the same English club in the competition is Cristiano Ronaldo, also for Man Utd (12y 110d).
