Alan Knill was full of praise for United's dominant second-half performance, as the Blades came from behind to win at Oxford on Tuesday evening.
A brace from Billy Sharp either side of Kieron Freeman's eighth of the season saw the Blades make it seven games unbeaten with victory at the Kassam Stadium and in the process, extend the lead at the top of table to eight points.
And understandably Chris Wilder's number two was impressed by what he witnessed after the break, remarking: "It was a super second-half performance after a difficult opening 45 minutes.
"We started brightly but the goal knocked us a bit, we couldn't get hold of the ball and Oxford pressed well.
"We got through to half-time though and the manager calmed everything down. We wanted to concentrate on our strengths and playing how we wanted to play and we dominated the second period."
Knill added: "We knew what to expect from Oxford, we went with Couttsy sitting with Basham and Fleck either side of him and that worked quite well, but when Jake (Wright) came off and we introduced Samir (Carruthers) it totally changed the shape of the game.
"They had to think more about Carruthers then and that allowed Coutts and Fleck to gradually dictate the game."
On Wright's early withdrawal and the absence of Mark Duffy, Knill concluded: "Jake's got a big gash on his nose, he went to hospital for stitches that's why he had to come off.
"Duffy missed out following a heavy challenge at Rochdale. He wanted to play but we opted to give him a break with 10 further games remaining because he is a big player for us."
