Robin van Persie scored either side of half time to give the Red Devils a 2-0 win over last season's surprise FA Cup winners.
The Dutchman opened the scoring in the sixth minute with an accurate header before doubling his and United's total just before the hour mark with a deflected shot from the edge of the area.

Was the result fair?
The term 'at a canter' certainly applies here. It may have been a nervy afternoon if United hadn't got an early goal but they did and from the moment Van Persie found the far corner with a pinpoint header, the Shield was never going anywhere else. As you can see above, Wigan managed just one shot - David de Gea won't have an easier afternoon all season.
The early goal settled the Premier League champions and to be honest, Wigan didn't offer any threat. When Moyes was offered the trophy by captain Nemanja Vidic at the end, the Glaswegian didn't hoist it up with much conviction. He knows that today was pleasant but no more than that. An easy-peasy start to what is sure to be a difficult season. Wilfried Zaha was selected to start and did OK. At times he tried too hard and will need to cut that out if he's going to perform in the top flight.
The Championship season began so well for Owen Coyle at Barnsley last week but he'll want to put today to the back of his mind as soon as possible. If Wigan are going to return to the top flight at the first time of asking, they're going to have to cope with European football as well as the 46-game Championship schedule.
Sports Mole's man of the match
Robin van Persie: A clear winner of today's man of the match is Dutchman Van Persie. He had such a strong debut season last term and looks like he'll continue that form this year after today's performance. The second goal wouldn't have gone in if James Perch hadn't deflected it but the first was class. Being able to place the ball into the corner with your head from over 12 yards out is a tough skill and executed perfectly by the number 20.
No stand-out winner here but we're going to have to give it to Perch for sticking out a leg when he could have left Van Persie's shot that was headed straight for Carson.
Mark Clattenburg had few contentious decisions to deal with today and also didn't need to use Hawk-Eye, which was in action for the first time in English football.
United: First up in the Premier League for United is a tough trip to Swansea in next Saturday's evening kickoff.
Wigan: The Latics will look to forget this match as quick as possible by continuing their winning start to the Championship season when they visit Bournemouth on Saturday.
