Speaking after Tuesday's win at Bury, Danny Wilson believes the Blades are starting to find their best form.
The 2-0 success at Gigg Lane saw United extend the unbeaten run to six league matches on the road and in the process put themselves within three points of second-placed Doncaster Rovers.
On United's second away win in four days, the Gaffer commented: "It is another great three points on the road and if we are to make a serious challenge for promotion these are the games we need to be winning.
"The last two away victories have put us within touching distance of the automatic places and that is exactly what we want with 15 games to go.
"The carrot is dangling in front of us if we can keep this momentum up and I remain sure we will be there or thereabouts.
"We have never doubted the lads, but when you lose senior players it is difficult to replace them, no matter how highly you regard your youngsters.
"The youngsters must earn their stripes and if we had put a team full of young lads out at places like Shrewsbury and Bury we would have been beaten.
"We had to stand up to Bury at times and use our experience wisely. It is no coincidence that when we are close to full strength the results start to improve and become more consistent."
Both scorers earned praise from the Blades chief after Tuesday's encounter.
Wilson added: "The goals that Jonathan (Forte) and Jamie (Murphy) scored will have done their confidence the power of good.
"Both lads are becoming a real threat in our forward play and, in particular for Jamie, that goal has been coming for a while. That is one of the reasons why we brought him to Bramall Lane."
