Paul Coutts felt the Blades were full value for Saturday's impressive success over Derby County at Bramall Lane.
Two goals from skipper Billy Sharp paved the way for another home maximum, with Jonny Russell scoring a bizarre own-goal too and Coutts says United got their 'rewards' for keeping the Rams under the cosh.
The midfielder commented: "It was a tough game and we knew it would be. The Gaffer had emphasised that we would need to be bang at it and in the first-half in particular we were.
"We weren't flattered to go in at half-time 2-0 up. We had to dig in at times in the second-half and we did to see the game out.
"Derby were a threat on the counter, but the majority of the first-half was played in their half and if you put teams under that amount of pressure you will get your rewards."
Coutts added: "They had their moments as the game progressed, they were always going to have a go at us and right until the end they threw everything at us, but we showed our spirit and determination and it was lovely to score the third at the end.
"This was always going to give us a gauge of where we are because Derby will be up there, I have no doubts over that, so to beat them at home is a great result."
