Nigel Clough insisted the players should take all the credit, following Tuesday's dramatic penalty shootout success over West Ham United at Upton Park in the Capital One Cup.
The Blades were 5-4 winners on penalties in the second round tie, with skipper Michael Doyle scoring the decisive spot-kick, after the game had ended 1-1 after extra-time.
With the score at 4-4, Mark Howard saved Enner Valencia's penalty, meaning the Blades were through if Doyle obliged and he didn't disappoint in front of the vocal travelling Unitedites, of which there was in excess of a 1,000.
Speaking afterwards, a delighted Clough beamed: "It was reminiscent of our terrific run in the FA Cup last season. It was backs to the wall at times and we made a number of fantastic last-ditch blocks in the second-half and extra-time.
"We were reasonably happy with the first-half performance, although we showed West Ham too much respect and conceded a poor goal.
"We told the players at half-time we needed to apply more pressure in the second-half to try and get back into the game and thankfully we did so within 15 minutes of the restart.
"West Ham showed how much they wanted to win the game with their three substitutions, but we held firm before scoring five brilliant penalties, which is often difficult in such circumstances."
The Gaffer added: "We have looked disjointed at times this season, but this was the first time we have looked strong, disciplined and compact as a team.
"There is still work to do, a lot to get to where we want to be, but we are certainly moving in the right direction and this victory will boost the confidence of the players."
