United could not build on Saturday’s 5-2 trouncing of leaders Burnley and could barely get going all evening, falling to defeat thanks to skipper Ben Wiles’ calm first-half finish.
They did have the ball in the net in the first half, Enda Stevens’ goal being ruled out for offside, and Oli McBurnie had a good chance in the second half, but United couldn’t find a way past Millers goalkeeper Victor Johansson and were sentenced to defeat.
Here’s how we rated United’s players on an evening to forget at Bramall Lane, which also saw John Fleck limp off with injury in the first half ...
13. Subs: James McAtee 5
An early introduction as Fleck made way and showed some promising moments and some frustrating ones as well. Later made way himself for Khadra Photo: Darren Staples
14. Chris Basham 5
Came on for Ahmedhodzic and played in midfield in a bid to give United some much-needed steel in the middle of the park Photo: Bradley Collyer
15. Billy Sharp 5
Looked desperate to impress from his introduction and seemed to be harshly booked for a challenge as he won the ball back high up moments after coming on. Flicked a late header wide from Khadra's cross Photo: Darren Staples
16. Came on for McAtee and injected some much-needed pace, trickery and directness into United's play
