A couple of penalties from Sadio Mane and Sheyi Ojo, plus second-half strikes from Daniel Sturridge and Xherdan Shaqiri,sealed the victory for Liverpool after a sublime first-half free-kick from Andreas Pereira.
There was a late change for United when the teams stepped out, with Eric Bailly replacing Chris Smalling in the backline as a precautionary measure. The Ivorian lined up in a back three alongside Tim Fosu-Mensah on the right of him and Axel Tuanzebe on the left. Matteo Darmian and Demi Mitchell provided support down the wings, while up front Alexis Sanchez led the line with support from Juan Mata.
