England international Rashford came on just after the hour mark and netted three goals in 18 minutes, first running clear to calmly slot in, then smashing in a terrific second, before drilling home a third in stoppage time.
Teenage forward Mason Greenwood scored his first goal in the competition, latching onto Paul Pogba‘s defence-splitting pass before drilling a precise, low finish into the far corner.
Greenwood produced another thumping effort straight at Peter Gulasci, while the visiting goalkeeper also kept out Anthony Martial‘s poked effort.
But when Martial was tripped in the box with three minutes to go, he converted the penalty in a thumping victory for the Red Devils.
