It was a record 16th triumph for the Reds in the traditional curtain-raiser of the season and the perfect way for Moyes to kick off his tenure.
Last season’s golden boot winner Robin van Persie took just six minutes to get off the mark for the new campaign with a superb headed finish from 14 yards, after being found by Patrice Evra’s floated cross from the left.
Chances were few and far between in the first period thereafter although Danny Welbeck was denied by a good reaction save from Scott Carson just before the break after a lovely turn and shot.
Carson could do nothing about van Persie’s and United’s second on 59 minutes which effectively ended the game as a contest. A nice passing move involving Evra, Cleverley and Welbeck ended with van Persie finding the net after his shot on the turn took a large deflection off James Perch.
It was a deserved victory for the Reds who were always in control against a Championship side that rarely threatened. United fans will hope this is the first of many trophies to come, this season and beyond.
