The winger intercepted a loose pass before bending a shot into the bottom corner in the fourth minute of stoppage time.
Tyrese Campbell opened the scoring as he finished off a devastating counter-attack from the Blades.

That miss came back to bite them when Patrick Roberts fed Eliezer Mayenda, who took one touch before firing clinically into the roof of the net.
