How many players on a soccer pitch
Basic Info
Football is divided into three types: standard football, indoor football (also known as five-a-side football), and beach football.
1. Standard football is the football game we usually see on TV, with 11 players per team, including 1 goalkeeper, and 2 teams per game, totaling 22 players.
2. Indoor football, 5 players per team, including 1 goalkeeper, 2 teams per game, a total of 10 players.
3. Beach football, 5 players per team, including 1 goalkeeper, 2 teams per game, a total of 10 players.

After watching many World Cup matches, have you ever thought about this question: why are there 11 players on each side of the stadium instead of 10 or 12?
This is related to the development history of modern football. Football originated in England. In the mid-19th century, football games became popular in schools and universities. Competitions on campus are often held in dormitories. At that time, each dormitory usually had 10 students and 1 administrator. Slowly, the game evolved into a mode of 10 players and 1 goalkeeper.
Because of the "restriction" of 11 people on each side, the British talent really planned the course and finally determined the uniform length and width standard of the course.
In this way, the "standard" of 11 players on each side in a football match was determined.
Interestingly, due to historical reasons, although the British have determined the length and width of the stadium, the length and width of the stadium in the Premier League are not completely consistent. Selhurst Park Stadium and Anfield Stadium are the two oldest stadiums in the English Premier League, built in 1924 and 1884 respectively. The stadium is very small, and the fans on the sidelines can even feel the breathing of the players on the field.
Later, football added commercial elements, which required the stadium to accommodate enough spectators while ensuring that every spectator could see the game clearly. The final standard football field was designed to be a rectangle with a length of approximately 100 meters and a width of approximately 70 meters.
Assuming the area of the football field is S and each team has N players. On average, the area occupied by each player is S/N.
Assuming this area is a rectangle, the side length of the rectangle is equal to the average distance between players d=square root (S/N). Now the attacking player has the ball, and the average distance between him and the defending player is close to D/2. If the player's speed is V, then the approximate time required for the opposing player to run towards him is td/2v. If the average running speed of a football player is V=5m/s. We also know that the area of a football field is approximately 7000 square meters. We can simplify the entire formula as T=8.4/square root n.
Draw an image and you will find that as the number of players N in each team increases, the time t left for players to control the ball becomes smaller and smaller. When each team has 11 players, the reaction time left for each player is approximately 2.5 seconds. He can stop the ball in one second, control the ball in one second, observe the surrounding environment and think, and then start dribbling or passing the ball in the next second.
This kind of game has both rhythm and excitement, and 11 players per team is a reasonable result.
2. Each team can have 1-2 substitutes during the game.
2. In each game, the head coach of each team can freely adjust the players on and off the field, but each team only has 3 opportunities to replace players in a single game, and the replaced players cannot play again.
3. Substitute players must be substituted before they can play.

But this raises a question, is such a personnel arrangement really reasonable?
The number of players on the field is closely related to the size of the field.Because of the "restriction" of 11 people on each side, the British talent really planned the course and finally determined the uniform length and width standard of the course.

How big should the football field be designed?
In the early days of football, the size of football pitches depended on how much space people could find. Later it was realized that a football pitch had to be big enough to at least ensure that a goal could not be scored from anywhere.Later, football added commercial elements, which required the stadium to accommodate enough spectators while ensuring that every spectator could see the game clearly. The final standard football field was designed to be a rectangle with a length of approximately 100 meters and a width of approximately 70 meters.
How to determine the number of participants?
To make a football match exciting, it is necessary to put pressure on the players. After receiving the ball, players must immediately know how to handle it. That is to say, the typical time for the opposing player to run towards the ball handler must be close to the time when the ball handler subsequently controls and moves the ball. If there are too few players and the distance is too far, the game will not be tense enough; If there are too many players and the distance is too close, and the players don't have time to think, the football game will be like a pinball game.Assuming the area of the football field is S and each team has N players.
