Danny Wilson declared that the Blades progression to the next stage of the Johnstone Paint Trophy was a job well done at Notts County.
Doubles from Shaun Miller and Harry Maguire paved the way for a comfortable 4-1 victory over the Magpies as Wilson rotated his playing squad, making the permitted five changes to his starting line-up.
On the success, he commented: "We played some very good stuff at times and the goals were executed very well, although the fourth might have been slightly fortunate!
"We gave a good account of ourselves against a very strong Notts County side; it was a great lesson for our youngsters. The lads coped well with what they threw at us, if you look at their team and bench you see what strength in depth they have.
"To come to Meadow Lane and produce that type of performance both individually and collectively is immensely pleasing."
Several players caught the eye in Nottinghamshire, giving the Gaffer food for thought ahead of the weekend's trip to Preston North End.
Wilson concluded: "Chris (Porter) showed exactly what he is about and Shaun (Miller) fed well off him. They have both put themselves firmly in the frame.
"We needed to see some lads in the first-team environment and in this instance they have all passed with flying colours.
"Everyone is contention for the weekend; the young lads in particular have started their progression towards league football."
