They made hard work of it, but in the end it was the Adnan Januzaj show at the Stadium of Light. The first half saw more of the disjointed football that has become the unfortunate blueprint for United under Moyes - and it was not long before they were behind.
Nemanja Vidic, who struggled physically against Jozy Altidore for the majority of the game, was culpable. The Serbian fluffed his lines and the ball ended up falling perfectly at the feet of Craig Gardner - who fired home to give United plenty to ponder when half-time came around, but not before David de Gea saved United’s bacon.
His terrific save from a header by the Italian international Emmanuele Giaccherini is being touted as the save of the season already with nothing else so far this campaign coming close.
The second half saw a much improved United come out firing, and it was then that the Belgian starlet came to the fore.
First he scored a calm effort after excellent build-up, before hammering home a left-foot volley in sumptuous style to make it two.
The only blip on his performance was a blatant dive which saw him booked.
The starlet then came off and despite late corners Sunderland could not find an equaliser, as they stay rooted to the bottom of the table - as United climb to ninth.
