United's Under 18s ran out comfortable winners in their final away game of the season, scoring four without response against Southern league title hopefuls Ipswich Town.
The Blades were on top throughout and rarely troubled by the hosts and had several chances within the opening minutes alone.
Leo Gaxha and George Broadbent both saw efforts saved from distance while Josh Scott saw an acrobatic effort go wide before Tom Weaver gave the Blades a lead with a superb header from Broadbent's free-kick.
United never looked back from that moment and were 2-0 up 10 minutes later. Good work from Scott down the right teed up Sam Ackroyd who fired home under the goalkeeper from the edge of the box.
The rest of the first half became a bit of a scrappy affair with some feisty challenges going in from the hosts but the Blades maintained their lead at the break.
The points were sealed soon after the interval when Scott headed home from close range after getting himself on the end of Jake Kelly's excellent cross.
With 20 minutes to go, Weaver added his second. It was another Broadbent free-kick but this time the ball was cleared to the edge of the box and the defender sent a first-time effort into the bottom corner.
Ipswich were reduced to 10 men shortly after for an off the ball incident and United saw the game out with ease for a well-earned three points on the road.
Blades: S. Kelly, Weaver, Brooks, Wilson, Williams, Barnes, J. Kelly, Broadbent, Ackroyd (Maguire 83), Scott, Gaxha.
Unused: Hiddlestone, Hackford, Skerritt, Viggers.
