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...
1. Casper Ankergren
Brilliant in the second half, making a vital save from Welbeck and denying Rooney under immense pressure at the death. Commanded his box from the first minute to the last. 8/10
2. Jason Crowe
Crowe's clearance off the goal-line from Rooney was a pivotal moment, and although Manchester United got some change out of him, it was less than they would have liked. 8/10
3. Richard Naylor
A captain's performance from Naylor. Never looked ruffled, never seemed worried and did not allow any more than the handful of chances that Leeds were bound to concede. 9/10
4. Paddy Kisnorbo
Every week his performances seem to improve, and he is unlikely to better the exceptional display he produced at Old Trafford. Absolutely awesome, in every way. 9/10
5. Andy Hughes
Obertan had his number initially, but Hughes experience came flooding through and Ferguson was forced to switch his wingers after the break. A fantastic day for the Manchester City fan. 8/10
6. Michael Doyle
Exactly the sort of player United needed in the heat of battle at a venue like Old Trafford. Fought to the death.. 8/10
