The 2005–06 Football League Championship (known as the Coca-Cola Championship for sponsorship reasons) was the second season of the league under its current title and fourteenth season under its current league division format.
Reading dominated the Championship, setting a new league record of 33 league games unbeaten between the opening day defeat by Plymouth Argyle and the loss at Luton Town in February; these were the only league defeats the team would suffer that season. On 25 March 2006 they clinched promotion to the top flight for the first time in their 135-year history thanks to a 1–1 draw away to Leicester City.[2] Coppell's team secured the league title in the following week, with a 5–0 drubbing of Derby County, and they would go on to set a new English league record for the number of points won in a season, with 106.[3]
