Chris Wilder was quick to praise the attitude of his players in the aftermath of Tuesday's convincing 3-0 over Shrewsbury Town at Greenhous Meadow.
After a goalless first-half, the Blades were quickly out of the blocks in the second period and Billy Sharp goals either side of Daniel Lafferty's first for United paved the way for a seventh win in an unbeaten run that now stands at nine matches.
The victory in Shropshire came just three days after the Blades put four past Port Vale at Bramall Lane and Wilder believes it's the players desire and determination to succeed that have been instrumental to the success.
The boss remarked: "We spoke before the game about not just expecting to be able to turn up and win the game and we were made to work extremely hard for the three points.
"Shrewsbury played direct, they got the ball forward and tried to get down the sides of us. They man marked Duffy so it was important Done and Sharp made their defenders work, but in the first-half we just lacked a bit of quality.
"We certainly stepped up a gear or two in the second-half and got our reward, our performance was excellent and most importantly clinical.
"We're getting to where we want to be and we're picking up results in the process. Our wing-backs played higher second-half and that got us going forward, with Lafferty in particular very impressive."
The Gaffer added: "We're now getting consistently high performance from quality players, but it is their work ethic that is impressing me the most, the way we are chasing teams down right to the final whistle regardless of the scoreline.
"When you work hard it normally allows your quality to shine through and at the minute things are falling into place. We demand good habits in both training and in games, it is winning tough matches like this on Tuesday nights away from home that get you to where you want to be."
