Nigel Clough was encouraged with aspects of performance, as the Blades drew 1-1 against Northampton Town at Sixfields on Tuesday night.
Andy Butler opened the scoring against the Cobblers, heading home a pinpoint Ben Davies free-kick in the first-half, but a Marc Richards penalty after the interval ensured the spoils were shared.
But the Gaffer was happy with the workout, he remarked: "We improved a bit from Saturday which was needed. We looked a bit stronger, fitter and sharper so that was good.
"As expected Northampton provided us with another stern test and we were more competitive than we were at Burton.
"We were in control for long periods, especially in the first-half and Chris Porter had two good chances before we scored from an excellent Ben Davies delivery.
"Unfortunately a misjudgement from George Long cost us the win because apart from the penalty we defended well.
"It was a successful exercise, the early injury wasn't ideal and it meant Ben Davies had to play 90 minutes, but apart from that we got the right amount of time into the legs of everyone else."
