Assistant Manager Alan Knill was full of admiration for the Blades after Wednesday's Checkatrade Trophy victory over Grimsby Town at Blundell Park.
Goals from Regan Slater on his debut, Jack O'Connell and the returning Leon Clarke, in addition to an Andrew Boyce own-goal, saw a youthful United line-up overturn a half-time deficit to run out worthy 4-2 winners on a bitterly cold night in Cleethorpes.
And Knill was quick to praise the group, he remarked: "I thought we were excellent from start-to-finish and we dominated long periods in the first-half, despite going a goal behind.
"In the second-half we were even better, we stepped up aa gear and thoroughly deserved our four goals and the victory.
"We had chances in the first-half, but we were clinical after the break and the attitude of the players was excellent in what was a game with little relevance to anything with both teams already out of the competition.
"But when we play, regardless of the competition, we want to win and thankfully we did that. We wanted to give some youngsters the chance to experience a first-team game and Grimsby were out to impress their new manager.
"Credit to our supporters that made the trip, we're just happy they saw a good performance and plenty of goals."
In addition to blooding several homegrown youngsters, the other major positive of the evening was the return to action two attacking players, in addition to another getting over an hour into his legs.
Knill added: "Leon (Clarke), Lavery and Matty Done all got some good minutes and we're delighted with that. Leon only trained with the full group on Tuesday but wanted to play and he will have got plenty out of that 25 minutes or so.
"The same with Matty, we didn't have him down to feature, but like Leon he put his hand up and was eager to feature, whilst Caolan got a first start and did well."
