Shaun Maloney scored the only goal of the game in the second half to give Roberto Martinez’s men a historic win and lift them out of the relegation zone and up to 17th place.
Despite claims that United should have had a penalty, Sir Alex Ferguson believes that the Latics were good value for their win.
“It was a disappointing night for us, in the first half we were totally dominated by Wigan,” he confessed to Sky Sports.
“It was of those awful nights that you sometimes get in football and it’s unavoidable sometimes.
“I think Phil Dowd had a disappointing game tonight but doesn’t take away from the fact Wigan were the better team and deserved to win.
“They play terrific football, are underrated, in a false position and really deserved the win tonight.
“The kind of football they play considering their position is a credit to their manager.
“Some of the football they play is outstanding, so we weren’t under any illusions, but the thing is we just didn’t cope with it,” he concluded.
The defeat sees United’s advantage at the top of the standings cut to five points; the Red Devils face Aston Villa at Old Trafford on Sunday.
