In association football, the formation describes how the players in a team are positioned on the pitch. Different formations can be used depending on whether a team wishes to play more attacking or defensive football. Formations are used in both professional and amateur football matches. In amateur matches, however, these tactics are sometimes adhered to less strictly due to the lesser significance of the occasion. Skill and discipline on behalf of the players is also needed to effectively carry out a given formation in professional football. Formations need to be chosen bearing in mind which players are available. Some of the formations below were created to address deficits or strengths in different types of players. 
  Indoor variants of association football, including: *Futsal, a variant of association football that is played on a smaller pitch and mainly played indoors *Five-a-side football, a variation of association football in which each team fields five players, rather than the usual eleven on each team *Indoor soccer, a game derived from association football adapted for play in an indoor arena such as a turf-covered hockey arena or skating rink  
In association football, eleven players are fielded in each match. The goalkeeper remains in the goal, and the remaining ten players are "outfield" players. 
NZIHL team rosters must be made up of a minimum 18 players and 2 goalies. Every roster must have a least 2 players eligible for the NZ U18 team and at least 3 players eligible for the NZ U20 team. If a player is a U18 & U20 rep he can only be counted once. Hence each roster must have a minimum 5 junior players. Each team is allowed an unlimited number of overseas imports on their roster, however there are limits to how many of these players can take the ice. Each team can have 4 imports plus 2 assimilated players (two full seasons in NZ). Australian players are classed as local players and import limits do not apply.
