United's U18s shared the spoils with their Barnsley counterparts in what was an entertaining clash at the SteelPhalt Academy at Shirecliffe.
The Blades conceded at the beginning of each half, but showed good character and deserved took a point in the end, with Jordan Hallam scoring twice from the penalty spot.
On a bitterly cold morning it was the visitors who started quickest on a snow covered pitch and went in front in just the fifth minute as a glancing header from a wide free-kick beat Perryman.
Gradually the hosts got back into the game and after Litchfield was denied following a swift counter attack, the Blades restored parity from the penalty spot in the 25th minute, with HALLAM converting confidently for his sixth goal of the season after the aforementioned Litchfield was upended.
But just as in the first-half, Barnsley scored almost immediately after the restart, netting with a shot from outside the area after the Blades failed to properly clear a long throw.
Although, within three minutes of falling behind for a second time, United equalised for a second time and it was that man HALLAM from the spot again after Hall was hauled down by the Tykes goalkeeper
Both sides huffed and puffed in search of a winning goal. Smith, Mallon and Gordon were all introduced in the final quarter of an hour for the home and Smith wasted two golden opportunities to snatch victory firing over and then wide from good positions.
But in the end the home side were forced to settle for a point as focuses switched to the FA Youth Cup second round clash at Chesterfield on Tuesday.
