Football is a team sport that requires a minimum of six players per team to play a match. The maximum number of players allowed on the field at the same time is eleven, with a total of twenty-two players. Each team of eleven players plays a football match, and teams may have fewer players than those if they have difficulty forming a team, but a match cannot start unless there are fewer than seven players available. The eleven players are divided into two groups: attack and defense.
Each player has a particular role and the task that they must perform in each play. The ball must be thrown to the side of the field by each team. If a team has fewer than eleven players on the field of play or in the end zone when a snap, free kick or fair catch is made, it is not a foul. The origin of the eleven-player rule is unclear, but it is likely that different associations across the country were playing a variant of football with their own rules, so there is likely to be some kind of trial and error in the decision.
It was not until 1965 that a substitute was allowed to replace an injured player and not replace another player for a tactical decision. This player must be agile enough to play defense, forceful and tough enough to play as a linebacker. The substitution is completed when a substitute enters the playing field; thereafter, the replaced player becomes a substituted player and the substitute becomes a player and can perform any reset. In addition to the eleven players on the field, teams may also have substitutes who can enter the game at any time. These areas can be further disseminated with players who play a certain role in the area they play and can even go further in that role by having a name associated with their style of play.
So you have eleven players on the field at the same time for your team, but that doesn't include your substitutes. A total of twenty-two players are on the football field at the same time, including eleven players in attack and eleven players in defense.
