The red half of Manchester went wild last night as United secured their 20th league title.
After a convincing 3-0 win over Aston Villa, Rio Ferdinand led celebrations in the dressing room at Old Trafford as the team enjoyed the end of yet another stellar Premier League campaign.
Manchester United manager Sir Alex Ferguson, 71, also swigged from a bottle of fizz and cheered wildly with his players, pledging to carry on in the job for another decade.
Meanwhile on the streets fans also enjoyed a drink in the city's pubs and bars as they toasted the Red Devils' success, and were later joined by the players who stayed out until after dawn.

Captain on the night Patrice Evra celebrated Manchester United's title in a different way by biting into a fake arm, the day after his nemesis Luis Suarez sank his teeth into Chelsea defender Branislav Ivanovic.
Pictures showed Evra brandished a fake arm, which was thrown onto the pitch from the stands, in what appeared to be an attempt to mock Liverpool's striker.
The pair have previous, though. Suarez was handed an eight-match ban after being found guilty of racially abusing the Frenchman during a match at Anfield in October 2011.

Robin van Persie bagged a magnificent first-half hat-trick to fire Manchester United to Barclays Premier League title glory, taking just 81 seconds to sweep home Ryan Giggs' knock-back.
Twelve minutes from the break he profited from more unselfishness from the veteran Welshman to complete the second three-timer of his United career.
In between he scored one of the best goals of the entire campaign as he followed Wayne Rooney's long ball throughout its 50-yard flight, waited for it to fall out of the sky then smashed a first-time volley into the corner.
It gave them an unassailable 16-point lead over rivals Manchester City and erased the pain of last season.

Sir Alex later vowed to carry on next season after leading Manchester United to their 13th Barclays Premier League title.
Fergie, who arrived at United in November 1986, has now won a staggering 38 trophies at Old Trafford.
The United chief, now 71, said: 'Winning the title has knocked ten years off me - these tablets are great.' Ferguson went on to claim van Persie's second, a volley beyond Brad Guzan after latching on to Wayne Rooney's 40 yard pass, was 'goal of the century.
The United chief added: 'Never mind goal of the season, it could be goal of the century.
'He did something similar for Arsenal, he's a special talent for sure.
He's been unbelievable all season. For the first six months he was incredible, but he had that little dry spell. This title means a lot to him'.
