The Isle of Man Football League is the senior football league on the Isle of Man and is run by the Isle of Man Football Association. Although the league is affiliated with The Football Association, it does not form a part of the English football league system.
The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with five teams from Wales, one from Guernsey, one from Jersey and one from the Isle of Man also competing. The system has a hierarchical format with promotion and relegation between leagues at different levels, allowing even the smallest club the theoretical possibility of ultimately rising to the very top of the system. There are more than 140 individual leagues, containing more than 480 divisions.
The English Football League Championship is the highest division of the English Football League (EFL) and second-highest overall in the English football league system after the Premier League. The league is contested by 24 clubs. Each season, the two top-finishing teams in the Championship are automatically promoted to the Premier League. The teams that finish the season in 3rd to 6th place enter a playoff tournament, with the winner also gaining promotion to the Premier League. The three lowest-finishing teams in the Championship are relegated to League One.
The Belgian Provincial leagues are the lower leagues for Belgian football. Until 2016, these were at levels 5-8 in the Belgian football league system however as part of the reform an extra level was created causing the provincial leagues to drop to levels 6-9. The provincial leagues are divided into 9 regional league systems. Each league system is itself divided into 4 levels. The number of leagues at each level depends on the province, but every province must have only one league at the top level. The best teams from the 9 first divisions can promote to the Belgian Division 3, the fifth and lowest level in the national leagues.

The Dutch football league system consists of two fully professional leagues and eight levels of amateur football leagues, the highest of which is called Tweede Divisie, formerly Topklasse. All the leagues are connected by a promotion and relegation system, but in order to be promoted to the Eerste Divisie a club has to submit a solid business plan to be approved by the Royal Dutch Football Association, as well as meet certain stadium demands, and some other demands that the association stated for all the teams in the top two leagues. That way it was possible that the IJsselmeervogels won the 2010–11 Topklasse, but was not promoted, because they did not want to be bound to these demands. FC Oss was promoted instead. The association obliges every team from the two fully professional leagues to contract 16 players full-time, in order to keep these leagues fully professional. In 2016 Tweede Divisie was reintroduced as the top amateur level and placed between the Eerste Divisie and the Derde Divisie.

The Divisiones Regionales de Fútbol in the Basque Country are ultimately overseen by the Basque Football Federation which operates Group 4 of the Tercera División RFEF, the fifth tier of the Spanish football league system divided among each of the country's autonomous regions. However, unlike most of the regions, the leagues in the sixth tier and below are organised by three separate federations, corresponding to the provinces of Álava, Biscay and Gipuzkoa.
