The Gunners' 4–2 victory over Wigan Athletic on the final day of the season saw them end 92 years of playing at Highbury before they moved into their new 60,000-seat Emirates Stadium.
Fellow newly promoted side Wigan Athletic, who were many pundit's tip for relegation in pre-season, defied the odds to finish 10th in their first season in the top-flight.
Everton crashed out of the Champions League early and were in the relegation zone by October, but a good run of results both after Halloween and in the new year saw them comfortably finish in 11th.
In contrast to the other promoted sides, Sunderland, last seasons Championship winners, were relegated with a league record low of 15 points, breaking the previous record that they set themselves in 2002–03, while West Bromwich Albion and Birmingham City both hit the 30-point mark and battled bravely, but both were unable to avoid relegation after dismal runs of league form (the Baggies going winless from February onwards, with Birmingham unable to shake off poor away form).
Although Crewe and Brighton had not spent long in the division and were considered to be punching above their weight, Millwall underwent a disastrous season, getting through five managers and four chairmen before relegation.
Leading goalscorer: Marlon King (Watford) – 21 Southend United surprised many by winning a second successive promotion, returning to the Championship after nearly a decade (when it was called Division One).
Colchester United also made the Championship for the first time in their history, but their promotion was tempered by the loss of manager Phil Parkinson to Hull City.
A highly competitive play-off race saw Barnsley emerge as winners, beating Swansea City at the Millennium Stadium 4–3 on penalties after both normal time and extra-time finished 2–2, to return to the Championship after three seasons of struggle in Division Two/League One.
