Nigel Adkins was full of praise for his players following Saturday's impressive 3-0 victory over Chesterfield at the Proact Stadium.
First-half goals from Alex Baptiste and Che Adams followed by Billy Sharp's 19th of the season in the second-half paved the way for United to take all three points from the trip to Derbyshire.
And Adkins was delighted with what he saw, remarking: "The players played well, it is another victory, three clean sheets on the spin and an unchanged team for a third consecutive week.
"The supporters were right behind the players, we scored three goals and comfortably won a local derby, so it was a good day all round."
The Blades boss is encouraged by how strong his team are finishing the Sky Bet League One campaign.
He added: "We were on the front foot, we could have scored more goals, should have really, but we were also solid defensively and played some good football too.
"Coutts and Hammond complimented each other well, as did Sharp and Adams. We have built some partnerships and hopefully moving forward we can have more consistency in team selection because undoubtedly it has helped in recent weeks.
"We now move on to the next game, we will take stock and go to Shrewsbury with a positive mindset and full of confidence.
"I want us to be the fittest team in the division, it takes time but we are in a lot better place now and that will only improve in the future."
