Manchester City have celebrated their first championship in 44 years after a dramatic 3-2 win against QPR on the final day of the Premier League season.
Sergio Aguero's injury-time strike saw City come from behind to secure the win it needed to clinch the title, barely minutes after Edin Dzeko drew the team level against the relegation-threatened Londoners.
"Football is incredible," a breathless City manager Roberto Mancini said as fans invaded the Etihad Stadium pitch.
"It's been a crazy season and a crazy last minute."
Mancini added. "We wanted this title and we deserve to win this title. This is for all our supporters, the club, the chairman and the owner.
"This is the perfect finale for a crazy season. We dominated this season for 38 games, but when we beat a team like United twice in one season we deserve this."
The stunning victory was enough to see off the challenge of defending champions Manchester United , which had been seconds away from celebrating a 20th league crown after a 1-0 victory at Sunderland.
The top two were level on points going into the final round, and City used its better goal difference to clinch its first title since 1968.
City was minutes away from the worst choke in league history as QPR took a 2-1 lead into the closing stages, despite losing hot-headed former City midfielder Joey Barton to a red card early in the second half.
City will be accused of buying the title as the club's billionaire Abu Dhabi-based backers have lavished almost £200m on an array of stars since taking over in 2008.
City won their first major trophy for 35 years last season, beating Stoke in the FA Cup final - but the achievement had to take joint billing with United's record 19th league title the very same day.
Despite the result, QPR retained their Premier League status at the expense of Bolton Wanderers, who were relegated after a 2-2 draw at Stoke City.
Meanwhile, Arsenal held on to third place and a guaranteed Champions League place with a 3-2 win at West Bromwich Albion, who waved farewell to their England-bound boss Roy Hodgson.
Tottenham must wait and hope Chelsea lose next week's Champions League final in order to book their place in Europe's top competition, as their 2-0 win at Fulham proved in vain.
