Bolton 1 - 0 Manchester U:Sir Alex Ferguson was sent to the stands as title-chasing Manchester United crashed to their first defeat since August.
Ferguson was dismissed by referee Mark Clattenburg for a half-time tunnel rant at a succession of minor decisions that had gone against his team.
And the United manager's mood could not have been improved by the sight of his side losing at Bolton for the first time since December 1978, nor the fact the matchwinner, Nicolas Anelka, was a man he has tried to buy himself on several occasions.
Not that Gary Megson will be too bothered about that as his first win as Trotters boss swept his new charges out of the relegation zone for virtually the first time this season.
Having survived the entire Sam Allardyce era without losing at Bolton, Ferguson felt sufficiently confident about registering another success against a side battling to get out of relegation trouble that he gave Cristiano Ronaldo the weekend off.
As the only member of his squad to play two Euro 2008 qualifiers over the past week, Ferguson had hinted he may rest his star winger, although with Wayne Rooney currently injured, it was definitely a gamble.
Ronaldo was missed in a disjointed opening period. But the real problem for the Red Devils was the absence of Nemanja Vidic with a back injury.
With Vidic missing, Ferguson turned to Gerard Pique as Rio Ferdinand's central defensive partner, leaving Wes Brown in the right-back role he has been filling for much of the season.
Pique appeared hesitant at times, though it was not in evidence when the Spain under-21 international came flying out to head away a free-kick Ivan Campo floated into the United box.
He missed, leaving Anelka on his own with time to control, turn and fire his seventh goal of the campaign past.
While Carlos Tevez beavered away without much success, as did Louis Saha, the wide pair of Ryan Giggs and Nani were virtually anonymous.
The Red Devils best opportunities fell to Owen Hargreaves, who screwed tamely wide on one occasion and forced a decent save from Jaaskelainen with a free kick. Tevez also missed a a late chance from six yards out.
