The supporters reaction said it all - after limping to a third consecutive defeat, the final whistle was greeted by a chorus of jeers.
As Louis van Gaal made the walk from his seat (which, again, he never moved from throughout the match), he was booed by a significant majority of the fans.
By contrast, the supporters applauded the players as they headed for the sanctuary of the dressing rooms.
Even MUTV, which can usually be relied upon to offer a degree of sympathy and support in tough times, was scathing in its post-match analysis of Van Gaal's sixth consecutive match without a win.
For us long suffering United fans, this really was the most benign of seasonal fare - you wouldn't want Van Gaal managing your Christmas.
You can imagine what it would be like as, despite spending a fortune at the butchers, he'd serve up a load of under cooked turkey and tasteless vegetables (all with a complimentary clipboard of course).
He would suck the life from the most joyous of celebrations.
Then there's Wayne Rooney.
This was the United captain's 500th appearance for the club and he was clearly keen to mark the occasion with a win.
He had the ball in the net as early as the ninth minute only to be flagged offside and his performance was summed up when-played through by Michael Carrick - he checked back, then his subsequent mis-hit cross thudded straight into the shins of a Norwich defender.
At one time a few years ago, Rooney would have torn into the box and smashed on goal but instead it was indicative of his recent struggles.
Roy Keane is an infrequent visitor to the ground these days following his very public fall out with Sir Alex and acrimonious exit from the club but was watching from the stands here.
How we could have done with his on-field belligerence, drive and never say die spirit in the Norwich game.
United are lacking real leadership at the moment and you suspect Keane, in his pomp, would not have allowed to slump to such a wretched defeat.
This side desperately lacks a leader in the Keane mould.
As the jeers and dissenting voices echoed across Old Trafford at the conclusion of this limp, lame, wretched, unacceptable performance, Van Gaal's much-trumpeted philosophy seems to be on its last legs.
Losing at Bournemouth is bad enough, but at home to Norwich does not suggest a club - or a manager - on the march to progress.
This cannot go on. Anyone got Jose's details...
