First-team coach Andy Garner says hardwork on the training pitch was the main reason behind Sunday's 3-1 success over Tranmere Rovers at Bramall Lane.
Goals from Jamie Murphy, Jose Baxter and Ryan Flynn saw the Blades end 2013 on a high note, extending the current unbeaten run to eight matches in all competitions.
Garner was on media duties after the game and praised United's quick start, which saw Murphy opening the scoring in the first ten minutes of the clash:
"It was a well-executed performance over the 90 minutes. The pressure was on a bit after Boxing Day but we responded positively and getting out of the traps quickly was vital.
"We really wanted to end the year with a home win, a small reward for our loyal supporters, who continually turn out in large numbers.
"We had a good few days on the training ground, working on getting on the front foot from the start and thankfully it all came together on the day.
"We have to start positively at home in front of our supporters because if we don't the opposition will rise to the challenge of playing at Bramall Lane.
"It is a massive occasion for the opposition and that is why we can't afford to start games slowly and give them encouragement, because we have paid the price for that already since we arrived.
Garner added: "The two wingers were fantastic, we created a lot of opportunities and all three goals were terrific finishes. We deserved more and how we didn't score more in the first-half we will never know.
"The first goal is massive, we keep stressing that to the players and when we get it, with the backing we have, it gives us a real advantage to build on."
