Chelsea secured the Premier League title in magnificent fashion by destroying 10-man Wigan Athletic 8-0 in a party atmosphere at Stamford Bridge on Sunday.
Nicolas Anelka struck twice and Frank Lampard, Salomon Kalou and Ashley Cole were also on target as Chelsea ended the season with 103 league goals, the first side to pass the century mark in the top flight since Tottenham Hotspur in 1963.
Chelsea, who prevented United winning a record 19th league title and a fourth in succession, can complete the double in next week's FA Cup final against Portsmouth.
"It's been a hard three years watching United win the titles year after year," Chelsea skipper John Terry told Sky Sports before being presented with the Premier League trophy for the first time since Jose Mourinho was coach in 2006.
"It's their turn to watch us today. Now we've got it back we want to do what they did. It's been an up and down year but this is what we've worked for."
It marked a fantastic start in English football for Ancelotti after 33 years playing and coaching in Italy.
"We played with continuity. We played as a team and at the training ground the players always did a good job," Ancelotti, who danced around the pitch with his players at the final whistle, told Sky Sports.
"It was time for Chelsea to win the title, but Manchester United and Arsenal were fantastic rivals."
BARELY CELEBRATED
The only blot on a day of celebrations was a show of petulance from Drogba when he barely celebrated Lampard's penalty which put the Blues 2-0 up, the Ivory Coast striker clearly upset that he had not been allowed the chance to go clear in the race for the Golden Boot.
All was forgotten by the end as Drogba joined his team-mates in the fun having scored a second-half hat-trick, although he did not get his hands on the match ball after Lampard belted it into the ecstatic crowd.
Any doubts that Chelsea would fluff their lines were wiped out in the opening half hour.
Anelka gave them a sixth-minute lead when he pounced on Florent Malouda's chested pass and Lampard's spot kick made it 2-0 after Gary Caldwell was red-carded for hauling him down in the box.
Kalou made it 3-0 early in the second half and the rest of the game was purely about whether Chelsea would break the 100-mark and Drogba would beat Manchester United's Wayne Rooney to the Golden Boot.
Anelka rattled in a fourth before Drogba got in on the act with a header, a penalty and a tap-in and Cole completed the rout. All that was left to do was spray the champagne.
It all went a bit flat at Old Trafford where United did what they had to do -- Darren Fletcher, Ryan Giggs and Park ji-Sung all on target - and the mood was not helped by the sight of Wayne Rooney limping off with a groin injury near the end.
UNITED FANS
United fans also clashed with police outside the stadium before kickoff as they mounted a demonstration against the club's American owners.
"We are disappointed but we know how difficult it is to win the Premier League, that's why we can congratulate Carlo Ancelotti and his team," United manager Alex Ferguson said.
"We have done well, we took it to the wire and it just wasn't to be. I've got no complaints. Losing this makes you appreciate our feat in winning the last three titles."
Arsenal, who had been in and out of the title race all season, made sure of a place in the group stages of next season's Champions League with a 4-0 home win over Fulham to hold off a late challenge for third spot from Tottenham Hotspur who finished fourth after a 4-2 defeat at Burnley.
Manchester City drew 1-1 at West Ham United, Aston Villa lost at home to Blackburn Rovers and Liverpool, who just crept into the Europa League places, were held 0-0 by Hull City who will join Burnley and Portsmouth in the Championship (second division) next season.
