Robin van Persie had struck in the 78th minute to equalise against Rene Meulensteen's men, after Steve Sidwell had given them an early lead.
Michael Carrick then hit what many thought would be the winner moments later. But Darren Bent was on hand to break United hearts once again in the 90th-minute.
And after seeing Man United drop yet more points at Old Trafford, it was a different emotion that Ferguson could no longer conceal.
The Scot has no doubt given many such looks over the years, although it was mostly his players on the end of it - and they usually responded with a winning goal.
Now, though, all Ferguson can do is watch, as David Moyes' side sit in seventh place, nine points off fourth-placed Liverpool.
On social media, meanwhile, several fans have made a mock image of Moyes' "tactics board"...
A far from ideal conclusion to a day to forget for the United boss, then.
What do you make of Manchester United's current predicament?
