With Ryan Bertrand out injured, it could have been very easy for Southampton to suffer in both attack and defence, but they didn't at all. Sam McQueen was a superb defensive force against Manchester United's only genuine attacking threat (Ashley Young), helping Southampton to deal with Young and prevented him from creating too many good chance. And when McQueen had the ball at his feet he moved it well and tried to create danger as best he could.
Stopping an opponent from scoring is as much about the defence as the player in front of them: the defensive midfielder was a superb shield, marshalling Southampton's entire midfield to close off space and prevent United from moving the ball about in front of the Saints defence. Romeu won 4/5 tackles, 2 clearances and 1 interception.
The colossal Jack Stephens at right-back often had to deal with a phenomenal amount of interplay between Manchester United's most dynamic players, but he did a decent job of limiting the amount of danger they could create for Southampton. Yes, he couldn't stop Mata, Mkhitaryan and Martial from creating space and sending crosses in, but he often limited the size of that space and quality of those crosses.
Southampton's veteran defender, who's remained at the club despite seeing all his defensive partners leave, put in an accomplished display at Old Trafford. Yoshida was powerful in the air, winning 3/4 aerial duels, he was solid on the ground too; winning 2/3 tackles and making 2 clearances as well.
There's also the penalty incident, in which Yoshida appeared to handle a ball that Jesse Lingard was bringing under his control. José Mourinho called it a certain penalty whilst referees have said it wasn't intentional. Looking at how Yoshida moves his arm towards the ball, it could be a lucky escape no penalty was given - but as he got away with it, we can only appreciate Yoshida's excellent display for Southampton.
After Southampton sold their star defender Virgil Van Dijk just a couple of days ago, many could be worrying for the future of their defensive solidity. But 23 year-old Wesley Hoedt showed why they need not fear.
Hoedt was colossal against Manchester United. Sure, he only won 2/4 tackles, but he made a colossal 10 effective clearances - more than any other player on the pitch. When there was a loose ball in the box, you could be sure Hoedt would be the one to get rid of it. When there was a dangerous cross rolling around the area? Hoedt.
It was a superb display and bodes very well for Southampton's future. Virgil Van Who?
