Much of the talk in the aftermath of this encounter has been Manchester United's terrible week, with defeat at newly promoted Bournemouth following their exit from the Champions League. Perhaps, though - with all this negativity - the scale of Bournemouth's achievement has been overlooked.
On the back of beating Chelsea at Stamford Bridge, they have now beaten the Red Devils at home. Seven years ago, they were fighting to stay in the football league while having to fight off administration. In the same year, their most recent opposition won the Premier League.
Now Bournemouth are the latest team to rise up through the divisions to achieve - what Eddie Howe has suggested as - one of the best weeks in the club's history. The recent results are even more surprising when you consider the injuries Bournemouth have.

All clubs have injuries at this stage of the season, but the Cherries have lost four key players for long periods of time, including new signings Tyrone Mings and Max Gradel. However, the squad players who have come in deserve huge credit for turning their fortunes around, with these back-to-back wins moving them clear of the relegation zone.
Bournemouth will be under no illusion they will still face a relegation battle, especially after other clubs have spent money in January.
Manchester United have spent £250 million under Van Gaal on transfers whereas Bournemouth spent just over £20 million in the summer - the gap in financial strength is enormous and makes Saturday's victory even more remarkable.
Yet Howe's side reminded the sport that money doesn't buy you success, recruiting the right players, implementing the perfect combinations and a balanced tactical approach is what really matters.
While Bournemouth have been unable to show off some of their summer signings, the current players are proving that attitude trumps wages every time.
Regardless of their fate this season, Bournemouth deserve credit for the way they have stuck to their principles and will end the season with respect from all fans. Long may the praise for Eddie Howe and his plucky underdogs continue.
