Erik ten Hag received a huge reaction from his side after making four changes to the XI that started the defeat to Brentford last weekend.
Goals from Jadon Sancho and Marcus Rashford in each half were enough to seal the win despite Mohamed Salah's late header for the visitors.
The Reds were on the front foot from the off, making our presence known at the back with Lisandro Martinez in the thick of it.
United showed a statement of intent early on, as Rashford was played in behind the Liverpool backline and almost got a shot away but for Virgil van Dijk intervening.
