It was a Manchester United performance of intensity, commitment and passion - and it was long overdue.
Liverpool simply couldn't contain them and the result was a deserved first win of the Erik ten Hag era following a display poles apart from the losses to Brighton and Brentford.
But the win also owed much to the bold changes in team selection made by Ten Hag even before a ball had been kicked.
Reacting to the catastrophic 4-0 loss at Brentford last weekend, the new manager dropped Cristiano Ronaldo, captain Harry Maguire, Fred and Luke Shaw, while also resisting the temptation to throw Anthony Martial straight back in.
