City fell into the bottom division for the first time in twenty-five years, with Chesterfield occupying the final relegation spot. Leading goalscorer: Billy Sharp (Scunthorpe United) – 30 Football League Two The four teams relegated from League One in 2005–06 would occupy the top four this season, sending Walsall, Hartlepool United and Swindon Town back up. Bristol Rovers won the play-offs however, returning to League One after six years. Torquay United had been both the last team to finish bottom under the old election system, and the last team to finish bottom of the League and survive due to the Conference champions not having a good enough ground. However, this season they finished bottom and dropped out of the League. They were joined by Boston United, who had voluntary arrangements in the 87th minute of the season's final game, but would still have been relegated even without the 10-point administration penalty. In a first since the introduction of automatic promotion and relegation between the Football League and Conference, Boston were relegated two divisions due to failing to pay footballing creditors, along with financial irregularities committed during their promotion season in 2001–02. Leading goalscorer: Izale McLeod (Milton Keynes Dons) – 21 Monthly awards Transfer deals The summer transfer window saw many high-profile moves.
