Red Devil’s coach, Louis van Gaal was vindicated after handing a rare start to the youngster.
It was the young Belgian first start since February as he was the only change from the side that defeated Tottenham.
Januzaj received a beautiful through pass from Juan Mata, beat Villa skipper, Micah Richards, before slotting pass Brad Guzan for United’s goal.
Aside the goal, it was yet another shambolic display by United in the first half, just as it was against Spurs at the Theatre of Dreams.
Wayne Rooney looked isolated all through the first 45 minutes as there was no real connection between the midfield and attack.
Aston Villa continued pressing for the equaliser in the second half with Manchester United comfortable sitting back and trying to catch their host on the counter.
The victory ensured that Manchester United maintained their hundred per cent record in the league this season to climb to the top of the Premier League table for the first time since August 2013.
