Manchester United ruthlessly squashed Wigan's dreams at the Millennium Stadium as they romped to a 4-0 win -the biggest League Cup final victory in history.
Wayne Rooney did most of the damage with a sensational display.
The brilliant England man scored twice, headed against the crossbar and proved totally unstoppable with a majestic performance which deservedly saw him crowned man of the match.
Sir Alex Ferguson caused a stir by leaving Ruud Van Nistelrooy on the bench but the controversial decision proved totally justified as the Dutchman's direct replacement, Louis Saha, also netted in a one-sided encounter.
Cristiano Ronaldo lashed home as well to give Ferguson his 17th major honour as manager but the first since Malcolm Glazer's £790 million takeover.
Wigan were urged on by 27,000 noisy supporters, an amazing achievement in itself given the Latics were a non-league outfit less than 30 years ago.
But they suffered an early blow when goalkeeper Mike Pollitt bent down to pick up the ball and immediately clutched his hamstring. The former Manchester United trainee did continue after treatment but eventually had to limp off to be replaced by John Filan.
Rooney, desperate to atone for United's FA Cup final failure on the same ground last May, was quick to show off his magic, brilliantly pulling down a Wes Brown long ball before cutting a cross back to Saha who could not make a clean connection with his volley.
Rooney almost scored himself not long afterwards when he met Gary Neville's curling cross with the firmest of headers which came crashing back off the crossbar.
United had a penalty appeal turned down by referee Alan Wiley when Park smashed a shot into Wigan skipper Arjan de Zeeuw.
Camara had a shot saved by Edwin Van Der Sar but it was United who were carrying the greater threat and Stephane Henchoz had to use all his experience to take the sting out of a Saha effort, allowing Pollitt to make the save.
It proved to be the keeper's last involvement before he headed to the touchline virtually in tears, to be replaced by Filan.
It was not long before United took a deserved lead and there was little surprise Rooney should be the man to fire them in front.
The build-up was pure Route One as Saha climbed to flick on Van der Sar's deep punch into the Wigan half. Rooney raced onto the loose ball, then broke free of Pascal Chimbonda and De Zeeuw before keeping his head to finish clinically past Filan.
Giggs almost set up a second with a left-wing charge but Rooney was unable to get sufficient power behind his volley as he tried to finish off the Welshman's hard work.
Bullard forced Van der Sar into a save with a 30-yard free-kick, then Brown made a couple of timely interventions, the second to clear a Roberts cross which looked like causing mayhem in the United box.
De Zeeuw escaped a red card when he took down Rooney on halfway, the Dutchman's own injury probably persuading Wiley to brandish the yellow card.
Having already used one of his three available substitutes in replacing Pollitt, Jewell opted against making any further changes at the break.
Wigan started the second half brightly and could easily have drawn level when Camara turned Ferdinand smartly inside the United box. The Senegal striker advanced on goal but Van Der Sar proved equal to his forceful angled drive.
Wigan kept up the pressure but Brown was again on hand to clear the danger when Camara threatened again.
Wigan's failure to find an equaliser proved costly as United quickly broke forward and grabbed a second. Ronaldo fed Neville from the overlap and the United captain wasted no time in drilling over a low crash which Saha should have finished off at the first attempt. Instead, Filan made the save only for the rebound to cannon into Saha's knee and bobble into the net to give the Frenchman his sixth Carling Cup goal of the campaign.
Wigan had one chance to get back into the game but Van der Sar held his nerve to punch Teale's cross over under pressure from Roberts.
Henchoz made a crass blunder when he attempted a clearance which went straight to Saha. The Frenchman immediately released Ronaldo and in turn the young winger shot into the net.
Within two minutes United had another, as Saha flicked a Giggs free-kick into Chimbonda's chest. Ferdinand reacted quickest and nodded the loose ball into Rooney's path and the youngster steered home his second goal.
Lee McCulloch was fortunate not to concede a penalty when he bundled Neville over in the area, then Park failed by inches to turn home Rooney's fine low cross.
