Simon Grayson's League One side travelled as major underdogs but left as heroes as they ended 28 years of Old Trafford hurt thanks to a lone Jermaine Beckford strike. Take a look at how we rated the players on a famous day for the Whites...
7. Jonny Howson
Gave Beckford his opportunity with a clever through-ball that caught Brown in no mans land. Battled like any Leeds lad should and looked shattered when he left the field. 8/10
8. Neil Kilkenny
Kilkenny's game is clearly suited to this size of stage, and he showed great composure by refusing to panic when space was limited early on. United's playmaker, yet again. 9/10
9. Bradley Johnson
His stamina was a major asset and the biggest threat to Leeds in the closing stages was the possibility that the United players hard work would take its toll. Covered a massive amount of ground. 8/10
10. Luciano Becchio
An epic shift from the most honest player in United's ranks. If the game had lasted for another 90 minutes, Brown and Evans would still have found him competing for everything. 8/10
11. Jermaine Beckford
Apparently he never performs when it matters. His priceless goal says otherwise, and the key to an upset was always going to be clinical finishing from Leeds. 9/10
12. Substitutes
Robert Snodgrass (for Howson, 77) - 7/10. Lubomir Michalik (for Becchio, 88) - 6/10. Aidan White (for Hughes, 90) - 6/10.
