United deservedly left Carrow Road with all three points, following an excellent second-half comeback in Norfolk.
Alex Tettey fired the home side in front just before the half hour, but two goals in seven minutes after the restart swung the game decisively in the Blades favour, with Enda Stevens and George Baldock the scores.
VAR played a role in the game, checking a number of decisions by referee Simon Hooper, but it helped United late on when Chris Basham's straight red was downgraded to a yellow following a lengthy review.
For the clash against the Canaries, boss Wilder made two changes following Thursday's loss to Newcastle. Mousset and McGoldrick started in attack, with McBurnie and Sharp named amongst the substitutes.
Inside a minute the Blades were on the front foot, but from the left, Fleck's low cross evaded everyone. In response, the home side a flurry of early corners, but Henderson's first meaningful save saw him comfortably deny McLean.
On 26 minutes United had their first sight of goal, but despite a poor clearance by Godfrey, McGoldrick's goal bound effort hit Zimmermann and subsequently made Krul's save much easier. Less than 60 seconds later City went in front as TETTEY fired home with a left-footed strike through a crowded box after the Blades failed to fully clear Buendia's corner from the right and the goal stood despite a VAR check, with the ball appearing to catch Zimmermann's hand in the build-up.
The lively Buendia continued to cause United problems, but his theatrical fall in the box failed to convince referee Hooper to award a penalty, despite claims from the hosts. United, who were now on the back foot, received two yellow cards in a matter of minutes before the break with Egan and Norwood cautioned for incidents involving Pukki and Buendia.
After a below par first-half showing, the Blades were out of the blocks quickly following the restart and scored twice in three minutes to turn the game on it's head. On 49 minutes, STEVENS rose above Aarons to head powerful past Krul's despairing dive. Moments later, BALDOCK went from provider to scorer, starting and finishing a move, that ended with him firing low and hard into Krul's far post.
As the hour approached, United had the ball in the net again, with Lundstram playing to the whistle and firing home, despite Hernandez seemingly fouling Basham in the box seconds before. VAR checked the goal, which was chalked off, but perhaps surprisingly failed to have a look at the early foul, which would have seen the Blades awarded a penalty.
Norwood and Mousset, who had picked up a knock following an awkward landing, were replaced by Bešić and Robinson respectively, before VAR finally gave the Blades a needed decision. Basham had been given a straight red after a lunge on McLean, but replays showed he had made no contact with his opponent and the tackle was subsequently downgraded to a yellow card and United's number six, who was on the touchline was beckoned by on to the field by the referee.
There were little over ten minutes remaining when McGoldrick came so close to adding a third, with two efforts in consecutive attacks. His first shot went inches wide of Krul's far post after a run by Bešić, before he fired over after a through ball from Lundstram. But at the other end, United were indebted to Henderson, who produced a world-class save to deny substitute Cantwell, one that he celebrated by with the Blades fans, by pointing to them and pumping his chest.
McBurnie took the place of McGoldrick, before Henderson kept his composure to claim a number of crosses that were thrown into his box as United saw out six minutes of stoppage time to claim the spoils and maintain the unbeaten run away from S2.
