The 21-year-old defensive midfielder laid a visionary pass to Demarai Gray who made light-works of two United defenders before unleashing a thunderous drive from long range.

Amartey was handed a starting role while attacker Jeffrey Schlupp was handed a place on the bench. Schlupp was later introduced in the game.

But a rampant United side consigned them to a 4-1 defeat at the Old Trafford with big-money signing Paul Pogba, Juan Mata, Chris Smalling and Marcus Rashord all got on the score-sheet.
