Wigan Athletic 1-0 Manchester United
Wigan Athletic produced a superb display as they beat a stunned Manchester United side 1-0 at a delirious DW Stadium.
Shaun Maloney's strike early in the second half proved decisive and the Latics deserved the three points as they kept the league leaders on the back foot for long periods.
The win lifts Roberto Martinez's in-form side two points clear of the relegation zone while United are now five points ahead of Manchester City at the top of the table.
Wigan made their intentions clear from the first whistle as they surged onto the attack while a listless United side struggled to get out of their own half in the opening 15 minutes.
James McCarthy had a shot tipped over the bar by David De Gea but Wigan thought they had taken the lead on the half-hour mark when Victor Moses headed a corner home.
Referee Phil Dowd appeared to have awarded the goal before eventually opting to rule it out on the advice of assistant Dave Richardson for what seemed to be a foul by Gary Caldwell on De Gea.
However, it seemed to be very harsh on the Latics who were also on the receiving end of two poor decisions at the weekend when they lost 2-1 at Chelsea.
United improved after the break but fell behind when Maloney beat Wayne Rooney before bending a great shot past De Gea.
Although they enjoyed lots of possession, United struggled to carve out many clear-cut goalscoring opportunities, although they were convinced they should have been awarded a penalty when the ball appeared to hit Maynor Figueroa on the hand inside the area, only for the referee to wave play on.
In the last few minutes it was Wigan that went closest to scoring as both Moses and Mo Diame almost made it 2-0 but in the end the Latics were still able to secure a famous victory.
