Football is a team sport with direct opposition, i.e. several players play against each other in a space they share, and that is more or less big. Except the player who plays as a goalkeeper, the other players are moving and will occupy the entire space being able to be distributed in infinite positions. To organize players in the space, lines and areas with different functions are established. This placement allows players to balance the strengths, weaknesses, both when the team has possession of the ball, and when it does not. Formations help and guide us to better understand the different placements and roles of the players on the pitch.
