Manchester United equaled the Premier League record by putting nine goals past nine-man Southampton – the second time Saints have lost 9-0 in as many seasons.
A red card for Saints’ Alexandre Jankewitz after only two minutes triggered a complete collapse for the visitors, who were on the end of the same scoreline against Leicester City in October 2019.
It is only the third time a team has lost 9-0 in the Premier League, with United also beating Ipswich Town by that margin in 1995.
The hosts brutally punished the Saints with goals from Aaron Wan-Bissaka, Marcus Rashford, Edinson Cavani, Bruno Fernandes, Scott McTominay and Daniel James, as well as an Anthony Martial double and a Jan Bednarek own goal.
A miserable night for Bednarek – and his side – was complete when he was sent off for the foul leading to Fernandes’ converted 87th-minute penalty.
