With 27 years of service and 13 Premier League trophies United could have done a lot worse than appointing Ryan Giggs as interim manager after the dismissal of David Moyes.
Norwich have the worst away record in the league this season and like United were also led by an inexperienced manager in Neil Adams.
United had a few good shots on target but failed to impress in the first half until Steven Whitaker fouled Danny Welbeck to gift United a penalty.
Wayne Rooney stepped up to score the first of what may be many in the Giggs era.
The Red Devils changed up their pace and tempo resulting in another Rooney goal within three minutes of the second half starting.
The shots kept coming and two goals from substitute Juan Mata secured all three points for what was a happier and more determined United than we’ve seen recently.
The Canaries, whose last two matches will be against Chelsea and Arsenal, end the weekend on 32 points and in the drop zone.
