Manchester United defeated Liverpool 3-0 at Old Trafford on Sunday to make it six consecutive victories.
Louis van Gaal's side are on a run that others may now find difficult to stop, with luck also on their side during their latest encounter.
Wayne Rooney put United ahead in the 12th minute before Juan Mata scored from an offside position five minutes before the interval.
That strike ensured United went in with their tails up and proved a decisive blow for a Liverpool side still smarting from their Champions League exit last week.
Mario Balotelli was introduced after half-time but the £16million man could not change the game and Robin van Persie ended the match as a contest with 19 minutes to play.
The result means United climbed to within five points of reigning champions Manchester City in second while Liverpool slipped to 10th.
