United's next generation capped a successful week by finishing the Northern Ireland Super Cup in third place.
The Blades youngsters put the disappointment of losing to Londonderry in the semi-final to one side, to beat tournament favourites Chivas Guadalajara 1-0 in the third/fourth place play-off with Sam Akroyd scoring the game's only goal.
Against the Mexican outfit, who retained possession excellently, United were resolute and well organised throughout and deservedly won the tie through Akroyd, after goalkeeper Marcus Dewhurst had saved a penalty.
Netting the winning goal and in the process scoring his seventh of the tournament, Akroyd went to claim the Golden Boot award.
Coach Ash Foyle concluded his thoughts on the competition, remarking: "We were still reeling from not making the final, but we ended on a high.
"We showed terrific belief and character against one of the best teams in the tournament. We more than deserved to finish in third place and the lads should be immensely proud of what is a fantastic achievement."
Meanwhile, closer to home United's development squad, which consisted largely of first-year scholars, beat Stockport County 5-0 at the SteelPhalt Academy at Shirecliffe on Friday.
Keegan Burton, Jake Ford, Reon Potts and a brace from David Parkhouse saw the Blades run out comfortable winners.
On Saturday, a more experienced Blades development squad drew 2-2 at Gainsborough Trinity.
Jordan Hallam got both goals, with the likes of Callum Semple, David Brooks and striker Jake Wright all featuring.
