It started badly. A throw-in turned into a free-kick for the home team, and a long ball that Manchester United back Phil Jones got it wrong. A few seconds later, John Fleck had bumped 1-0 with his knee.
At the beginning of the second half also came 2-0 before Manchester United came back, despite the team not playing very well.
Three young proprietary products stood for the pickup, and the turnaround: 19-year-old Brandon Williams shot 1-2, 18-year-old Mason Greenwood 2-2 before incumbent star Marcus Rashford made 3-2.
But Sheffield United got the last word. One post, a couple of bounces and then Oliver McBurnie shot 3–3 on volley through David De Gea's hands.
