The story
The real season.
On 23 October City won 6–1 at Old Trafford: Balotelli twice, Agüero, Silva and Džeko twice, with Evans sent off early in the second half. It was United's heaviest home defeat since February 1955, and it mattered more than anyone knew. Had it finished 2–1, the two clubs would have ended the season with identical records, and Premier League rules would have required a play-off.
City were top on Christmas Day for the first time since 1929, 44 points to United's 42. On New Year's Day Ji Dong-won rounded Joe Hart and scored for Sunderland with the last kick of the game. On 11 March City lost at Swansea and gave up the lead for the first time in five months. On 8 April Arteta's 87th-minute goal at Arsenal left them eight points behind with six games left, and the BBC wrote that their title hopes were “in tatters”.
Then United slipped. They lost 1–0 at Wigan and drew 4–4 with Everton, and on 30 April Kompany's goal in the derby put City top on goal difference. On the final day the clubs started level on 86 points. United won 1–0 at Sunderland. At the Etihad, QPR led 2–1 until Džeko equalised in the 92nd minute. Barton had been sent off for QPR. Then, 15 seconds after United's final whistle, Agüero scored in the 94th minute. It was the first Premier League title decided on goal difference, and City's first English top-flight title since 1968.
Without City none of that final afternoon survives, and the table below has a new champion and a new runner-up.
