EFL League One

The English Football League One, known as Sky Bet League One for sponsorship purposes or simply League One in England, is the second-highest division of the English Football League and the third-tier overall in the English football league system.

Introduced in the 2004–05 English football season as Football League One, it is a rebrand of the former Football League Second Division, which itself is a rebrand of the now-defunct Football League Third Division before the 1992 launch of the Premier League.

Fleetwood Town held the longest tenure in the division following promotion from League Two at the end of the 2013–14 season until their relegation this season. There are eight former Premier League clubs currently competing in this division; Barnsley (1997–98), Birmingham City (2002–06, 2007–08 and 2009–11), Blackpool (2010–11), Bolton Wanderers (1995–96, 1997–98, and 2001–12), Charlton Athletic (1998–99 and 2000–07), Huddersfield Town (2017–19), Reading (2006–08 and 2012–13), and Wigan Athletic (2005–13).

Structure
There are 24 clubs in this division. Each club plays each of the others twice. Three points are awarded for a win, one for a draw, and none for a loss. At the end of the season a table of the final League standings is determined, based on the following criteria in this order: points obtained, goal difference, goals scored, an aggregate of the results between two or more clubs (ranked using the previous three criteria), most matches won, most goals scored away from home, fewest "penalty points" based on yellow and red cards received, followed by fewest straight red cards for certain offenses. If two or more teams are still tied after examining all of these criteria, they will share the higher place between them. The only exception would be if the tied teams span the boundary between 2nd and 3rd, 6th and 7th, or 20th and 21st place, in which case one or more play-off matches would be arranged between the tied clubs.

At the end of each season the top two clubs, together with the winner of the play-offs between the clubs which finished in the third to sixth positions, are promoted to EFL Championship and are replaced by the three clubs that finished at the bottom of that division.

Similarly, the four clubs that finished at the bottom of EFL League One are relegated to EFL League Two and are replaced by the top three clubs and the club that won the fourth to seventh place play-offs in that division.

Milton Keynes Dons has spent 15 seasons in League One, the most of any team. Oldham Athletic's single 14-season consecutive spell was the longest of any team. The team with the current longest tenure is Fleetwood Town, who have been in League One continuously since the 2014–15 season. Rotherham United and Peterborough United have had the highest number of separate spells in League One with five each.

Financial Fair Play
Beginning with the 2012–13 season, a Financial Fair Play arrangement has been in place in all three divisions of the Football League, the intention being eventually to produce a league of financially self-sustaining clubs. In League One, this takes the form of a Salary Cost Management Protocol in which a maximum of 60% of a club's turnover may be spent on players' wages, with sanctions being applied in the form of transfer embargoes.
