Chris Wilder conceded it was not United's best performance of the season but was delighted with the grit and determination displayed in Saturday's 2-1 success over MK Dons.
Stefan Scougall, back in the team to replace the injured Matt Done, scored the first and played a major role in setting up Billy Sharp's winner in front of Bramall Lane's biggest crowd of the season.
"It was a tough game," commented the Blades chief. "MK Dons are in a false position, they have a good away record and good players, you only have to look at their bench to see that. We got off to a great start and that is a big three points for us.
"It was wasn't our best performance but you look at the opposition and take that into account. The reaction from our lads when they equalised was excellent the 10-15 minutes afterwards, we dug ourselves out of a hole. I think MK Dons will pick points up against the top sides so that's a fantastic result for us.
"They are difficult to play against and we had to change our shape on a couple of occasions. Fleck and Coutts moved all across the midfield and we brought Basham out from the back."
On the loss of striker Done, who fractured his jaw in the draw with Bradford City last week, Wilder added: "We will be without him for a couple of weeks, he cannot have any contact or head the ball. We will assess him but Scougall came into the team and did very well and so did Lavery when he came off the bench."
