United were forced to settle for a share of the spoils after a late Paul Dummett equaliser earned Newcastle a deserved draw in a thrilling, see-saw match on Tyneside.
This was not a game in keeping with our season: exciting, open and entertaining, we had led 2-0 through Wayne Rooney's penalty and Jesse Lingard's breakaway goal before Georginio Wijnaldum and Aleksandar Mitrovic pulled the hosts level.
Rooney fired United ahead again only for Dummett to thump home in the dying moments to make it 3-3 and end a run of four consecutive losses for the hosts.
United came flying out of the blocks and having gone close through Ander Herrera, took the lead after only nine minutes when Chancel Mbemba handled Marouane Fellaini's header and Rooney converted from the spot.
The skipper was simply magnificent and after he fired narrowly wide of Rob Elliot's post, he was instrumental in the second goal six minutes before the break.
Picking the ball up just inside the Newcastle half, he rode two Newcastle challenges and rolled the ball through for Lingard to fire in an excellent finish.
The hosts had hit back within three minutes, though, as Wijnaldum- whom had earlier forced an excellent save from David De Gea- made no mistake from similar range after he slammed home from Mitrovic's knock down.
Jesse Lingard then missed from eight yards out with the goal gaping from Herrera's cut back and that was a miss that came back to haunt the visitors as Louis van Gaal's soon found themselves under siege.
Ayoze Perez forced a fine save from De Gea and Moussa Sissoko lashed an effort narrowly wide but the pressure finally told as the Magpies pulled level on 67 minutes.
Mitrovic was grappled to the ground by Chris Smalling from a corner and the striker dusted himself down to roll in the resultant spot-kick.
Back came United though and, having weathered the storm, we went ahead for the third time in the contest through Rooney's magnificent 25-yard strike.
Fellaini then should have put the game beyond doubt after substitute Memphis had superbly picked him out, but the Belgian's header lacked power and was easily saved by Elliot.
It looked as though that would not matter, but Newcastle had other ideas and rallied again as Dummett slammed in a deflected drive from the edge of the area in the final action of a wonderful match.
Overall team performance: 7.5/10
United Faithful Man of the Match: Wayne Rooney. Scored two and set up the other. Magnificent.
