The Blades had to come from behind to take all three points, after going behind early on, while they withstood a late Cardiff onslaught after they pulled one back with a few minutes remaining.
Victory means Paul Heckingbottom has taken six points from his two games in permanent charge. Here’s how our man Danny Hall rated United’s players…
Lovely ball with the outside of the boot set Sharp free on goal but the skipper couldn't beat Smithies. Lit up the game with a superb equaliser and added two assists for good measure. What an impact he has made since arriving on loan Photo: Ashley Crowden
Heavily involved early in the game on the left of United's front three, and played a nice ball through for Sharp in the build-up to Morrison's red card. Got on the scoresheet himself to make it 3-1 Photo: Ashley Crowden
Came into the side with Brewster injured and had two brilliant early chances to open the scoring, but he was denied by Smithies on both occasions. Was fouled by Morrison when one-on-one, seeing the City captain sent off, and eventually got the goal he wanted before making way for McBurnie Photo: Ashley Crowden
Received an interesting reception as he replaced Sharp as a former Swansea man, and was denied a tap in by a brilliant tackle from Nelson Photo: Simon Bellis
