Nigel Clough was understandably delighted with Saturday's win over Port Vale at Bramall Lane.
Jose Baxter's first-half penalty settled the contest in United's favour and given results elsewhere, Clough acknowledged the importance of returning to winning ways as the Blades look to strengthen their grip on a play-off spot.
Reflecting on a hard fought three points, the Gaffer remarked: "It wasn't a brilliant game and we weren't sparking but the clean sheet was crucial and it was probably our biggest three points of the season in the circumstances.
"We started the game as we had hoped and for half an hour we were very good and could have easily been more than one goal in front, although Port Vale had their moments.
"At half-time, Tom Pope came on and they went more direct, but Basham and Brayford dealt with him brilliantly.
"We were a bit nervy, the crowd were too, there was a lot at stake and we knew the importance of keeping a clean sheet and thankfully we did."
Clough added: "It was a game with a lot a fouls in it, although nothing too bad at all really, the worst challenge was for the penalty, which was absolutely blatant.
"We still made the wrong decisions at crucial times offensively as we looked for that game clinching second goal, non more so than when Kieron Freeman tried to put the ball on a plate for someone to tap in when he should have shot hard and low into the corner in the second-half.
"But that will come with confidence and the three points are all that mattered on the day."
