Alexander Isak's eighth goal in his last six Premier League games gave Eddie Howe's side the perfect start at Old Trafford, with Joelinton doubling their advantage before the break.
United could have been out of sight before the break, with Sandro Tonali hitting the post at the end of one of a host of opportunities carved out by the visitors as they cut through a beleaguered Red Devils outfit.
In the end the two goals were enough for the Magpies, who are just three points off a top four spot now as they look forward to a promising 2025. The players celebrated in front of the travelling supporters at the end, and Harriet Massey was there to capture all the best moments for this newcastleunited.com gallery.
