David Weir insists United's pre-season preparations are heading in the right direction after Saturday's 3-1 success over Bury at Gigg Lane on Saturday.
Goals from Jasper Johns, Jamie Murphy and Stephen McGinn saw the Blades recover from a goal down to complete a third win in four friendlies to date.
The Gaffer said the most pleasing aspect of the victory was upping the intensity of the performance, in particular developing the younger members of the squad.
Weir remarked: "Being unbeaten is not the be all and end all, but winning games is always nice. The main aim is to get equal minutes into the players and thankfully, touch wood, we are avoiding injuries.
"Until this game it has been purely a fitness exercise and to an extent that remains the priority, but also the football has been good, which is pleasing."
He added: "Of course, there is room for improvement; you would expect that at this stage in pre-season. It was a younger group in the first-half, but I want to get all the lads to the same fitness levels.
"In the second-half we were more experienced and that told in the end, but the youngsters also acquitted themselves brilliantly."
