But who caught the eye for the Blades? Our man at the game gives his player ratings from the game.
1. Dean Henderson 7
Made one of his best saves in a United shirt, to keep out Adams' powerful header in the first half, and was generally safe in his handling and kicking. Was named man of the match in the fans' vote Photo: John Walton
2. George Baldock 6
Twice got in good positions down the right early in the game after a good ball from Norwood, but the chance was sniffed out by the defenders. Wiped out by Vestergaard for the free-kick from which United thought they'd scored Photo: John Walton
3. Chris Basham 6
Struggled to keep up with lively Boufal early in the game but grew into it as it went on, and denied the Southampton man with a superb last-ditch tackle when anything else would have surely been a goal, or a red. Subbed off Photo: Richard Sellers
4. John Egan 6
Was adjudged to have been offside when McBurnie tapped home what United thought was the equaliser - was he interfering? He didn't seem to touch the ball. Otherwise kept the lively Adams at bay for most of the game Photo: John Walton
