Scott McTominay, Marcus Rashford and Anthony Martial grabbed the Reds’ goals, but it could have been an even clearer margin of victory, had Ole Gunner Solskjaer's men converted two VAR-awarded penalties in the first half.
The game’s early moments were an indication of what was in store at Carrow Road, with plenty of entertaining, attacking football, and it was the hosts who created the first real chance of note in the fifth minute.
Right-back Max Aarons bounded down the wing and his side-footed cross was met by Todd Cantwell coming in from the opposite flank. However, the midfielder’s shot sailed just over David De Gea’s crossbar.
