FC United, the semi-professional team formed by disillusioned Manchester United fans, beat Rochdale 3-2 to secure a memorable FA Cup victory on Friday.
The side from the seventh tier of English football, founded after United`s takeover by the Glazer family, reached the second round with a dramatic late winner by Michael Norton.
The FC United number nine appeared to kick the ball out of Rochdale keeper Josh Lillis` hands before tapping into an empty net but referee Geoff Eltringham allowed the goal to stand.
The visitors took the lead before a crowd of just over 7,000 with a neat chip from Nicky Platt before Jake Cotterill doubled their advantage thanks to a thunderous long-range shot.
Their League One (third division) opponents pulled a goal back when Anthony Elding headed home from close range and looked to have earned a replay when Craig Dawson headed an equaliser with 13 minutes to play before Norton`s added time winner.
