Nigel Clough felt his side were good value for the 2-0 win over ten man Bradford City at the Coral Windows Stadium on Saturday evening.
A first Blades goal for Bob Harris and a well taken second from substitute Marc McNulty in front of the live Sky Sports cameras were enough for the visitors, after City played nearly the entire second-half a man down after skipper Stephen Darby's sending off for two bookable offences.
Speaking in the aftermath of the victory which sees United climb to seventh in Sky Bet League One, a delighted Clough said: "We are pleased, it was a deserved three points and a much needed clean sheet.
"In the first-half we got the ball down and kept our composure in what was a difficult atmosphere and a lively start by the opposition.
"We created two or three good opportunities and on another day Jose (Baxter) would have a couple of goals, but we should have worked their goalkeeper more in the opening 45 minutes.
"We looked solid at the back and restricted Bradford to very few chances, particularly in the first-half when they would have been looking for a fast start and an early goal.
"In the second-half we are fortunate when the lad hits the post with his header from close-range, but it was a superb save from Mark Howard to deny Alan Sheehan."
On the decision that swung the game in the Blades favour seconds into the second-half and how professionally his players approached playing against ten men, Clough remarked: "The second booking for Stephen Darby was for exactly the same thing that Jamal Campbell-Ryce got booked for on the stroke of half-time, the referee was consistant.
"We had to be patient after his dismissal, we needed to get good posession of the ball which we did and gradually we wore the opposition down, like we did against Leyton Orient, but sometimes it does take something a bit special to break the deadlock.
"Bob Harris has got a terrific left foot and his goal was a fantastic clean strike."
