United's U18s earned a point away at Crystal Palace in dramatic fashion in a fierce contest.
A late Reon Potts brace including a penalty and a last gasp equaliser got the Blades a share of the spoils against the leaders of the south division.
Palace went ahead after just 11 minutes with a cross to the back post headed beyond the reach of goalkeeper Kelly.
The hosts would go on to control the majority of the half and had two chances in the space of a minute to double their advantage. A header flew just over and an effort from a low cross went inches wide.
The Blades looked to find an equaliser towards the end of the first-half but Parkhouse was denied well by the Palace goalkeeper from just inside the box.
After the break United continued to push forward and the home goalkeeper was required to keep out Parkhouse and Potts respectively.
With just five minutes of normal time remaining United were presented with a golden chance to equalise as Gordon was brought down and a penalty was given. POTTS stepped up and slotted home to bring the Blades level.
The game looked lost however, as in added time a curling effort form 25 yards found the top corner and Palace were back ahead.
But the young Blades didn't give up and in the sixth minute of added time POTTS popped up to equalise and earn a deserved point.
Blades: S. Kelly, Williams, Boyes, Neal, Weaver (Gordon 60), Ferguson, Cravey (Capello 45), Broadbent, Parkhouse (Kelly 74), Potts, Teeluck.
