Rhian Brewster put the Blades ahead in the first half before his replacement Billy Sharp came off the bench to score in the second.
Here’s how we rated United’s players…
5. Ben Davies 7
A lovely clipped ball over the top send Stevens free down the left, but the left-back seemed in two minds whether to shoot himself or try and play in Brewster and his cross was blocked. Did brilliantly to get back and intercept as City had two men racing clear. Caught sloppily on the ball in injury time and booked after fouling his man

6. Enda Stevens 7
Instrumental in the build-up to Brewster's opening goal as the Blades got more joy down the left than they did down the right in the first 45 minutes. Good in the second half, too, both on and off the ball

7. Ollie Norwood 7
Played a brilliant pass to McGoldrick in the build-up to Sharp's goal, and got injured for his troubles. Replaced by Berge

8. Conor Hourihane 6.5
Also played a part in Brewster's opener as he combined with Stevens but should have done better with his pass in the second half, when he sprung the offside trap but couldn't find Gibbs-White in acres of space with his square ball. Replaced by Osborn after a decent display
