Nottingham Forest's under-18s missed out on the FA Youth Cup as Manchester United ran out 3-1 winners in the final at Old Trafford.
But the clash was mired in controversy in the 76th minute when Zach Abbott fouled Alejandro Garnacho with a penalty being awarded despite replays showing the incident occurred outside the area.
The score was 1-1 at that stage after Warren Joyce's side had fought back to level through Josh Powell but Garnacho put United 2-1 in front as he scored from the spot.
