West Ham dumped holders Manchester United out of the Carling Cup with a stunning 4-0 victory inspired by Jonathan Spector's first goals in English football.
Spector had never scored during his six seasons in the Barclays Premier League but here the USA defender struck twice to begin a rout that sent Hammers fans delirious.
Further damage was done by Carlton Cole after the interval with the England marksman pouncing twice to bring feeble United crashing back down to earth after their 7-1 drubbing of Blackburn.
Spector and Cole were brilliantly supported by Victor Obinna with the Nigerian forward, on loan from Inter Milan, having a hand in each goal.
Manchester United manager Sir Alex Ferguson made 10 changes to the side that hammered Blackburn last weekend with only Anderson remaining, but the manner of this defeat will still prove difficult to stomach. Experience was supplied by the likes of Ryan Giggs, Darren Fletcher and John O'Shea but they also wilted in the face of West Ham's onslaught.
Controversy reigned in the 16th minute when West Ham scored through Obinna - only to have the goal ruled out for offside. Obinna's shot deflected off Spector and the linesman had made the correct decision, but the Hammers were incensed.
Any sense of injustice was soon remedied, however, when Spector nodded West Ham ahead. Obinna supplied an exquisite chip that Spector, having crept inside Fletcher, headed into the net.
In the 37th minute the home side's ascendancy was rewarded once more. The hapless Fabio was involved as his attempted block of Obinna's shot instead fell into the path of Spector who blasted home from close range.
United were pouring forward as the expected fightback began in earnest, only to be halted in their tracks in the 55th minute when they were caught on the break. The superb Obinna was the supplier with his inch-perfect cross met by Cole, who headed the ball home.
There was still more to come from West Ham, however, as little over 10 minutes later Cole slammed home his second after being set up by Obinna.
