United's U23s deservedly returned to winning ways with a dominating display against QPR on Monday afternoon.
Caolan Lavery netted an early penalty, before further strikes from Ben Whiteman, David Brooks and substitute Jordan Hallam put the Blades in complete control, with Ebere Eze's late goal proving nothing more than scant consolation for the R's.
Trialist Reece Brown completed a full game, whilst Cameron Stewart who is also training with the club, played 77 minutes of the fixture at Imperial Harlington.
Inside the opening 10 minutes there were chances at both ends. Lavery was denied well by Lumley, whilst in response Darbyshire forced Ramsdale into a smart save.
But three minutes later, LAVERY wasn't to be stopped. Having used his pace to get in behind the home defence he drew a foul in the box from Frost, before dusting himself down to send Lumley the wrong way from the spot.
The Blades doubled the lead within a minute, as WHITEMAN timed his run perfectly to head home Chapman's cross. Two very nearly became three, but Lumley rushed out of his goal to deny Lavery his second.
The Blades were bossing the game and on the stroke of half-time, the R's were again indebted to Lumley who made two reflex saves in a crowded penalty area to keep the scoreline respectable.
The early exchanges of the second period were scrappy, although the home side through Bowler and then Folkes had a couple of speculative efforts on goal, but neither seriously troubled Ramsdale.
The Blades burst back into life in the 71st minute to gave themselves an unassailable advantage, after Chapman had been denied at the near post by Lumley, the home goalkeeper was powerless to prevent BROOKS from blasting home and in the 80th minute substitute HALLAM got in on the act to make it four.
The only downside to a near perfect afternoon in the capital was the late concession of a goal to Eze, but it mattered not as the Blades notched a second win of the season and a first since the opening day.
