United already have a piece of silverware in the trophy cabinet this season.
That comes following a Development squad's recent trip to the Netherlands, where they won the SP Lochem U19 Tournament.
United played two friendlies and four competitive fixtures whilst on tour and won every game.
Having beaten Arminia Bielefeld and FC Dordrecht in warm-up fixtures, the United youngsters overcame De Graafschap in their first group fixture, with Reon Potts and Jake Kelly on target.
The Blades then overcame Crewe Alexandra, thanks to a goal from Sam Ackroyd, before beating hosts SP Lochem 2-1 in their final group fixture, with Ackroyd bagging a brace.
That set up a final again against Willem II and Zak Brunt scored the only goal of the game, latching on to Kelly's flick on, as United stood firm under heavy pressure to secure a deserved moment of glory as they lifted the trophy.
