Nigel Clough felt the Blades were full value for their vital victory at Gillingham on Wednesday night.
Speaking after Conor Coady's decisive strike at Priestfield, which lifted United up to 18th position in the League One table, Clough praised his players for their application.
He remarked: "It was a brilliant win and a fantastic second-half performance.
"I didn't think we were at our best in the first-half, but the manner of our performance after half-time was very pleasing, we were never just hanging on.
"We looked like building on our lead and thoroughly deserved to take three crucial points home with us. I don't think Mark (Howard) had a serious shot to save and that is testimony to how well we defended."
The Gaffer was also pleased with how his troops handled a change from the usual 4-4-2 set-up, he continued: "We changed the formation in the absence of John Brayford and the three centre-halves gave nothing away.
"On the back of Sunday's terrific win, to come to Gillingham on a Wednesday night and get three points and a clean sheet, means this is probably our best result of the season.
"We were more comfortable than I thought we would be, but that was credit to us, rather than a slight on the opposition."
