The Game System

The concept of system refers to the arrangement/location of the players in relation to the different demarcations for the offensive game, so that 50% of the pitch is occupied, in depth, in breadth and effectively.

The game system used involves different considerations:

• The existence in a demarcation of one or two players.
• The existence of a demarcation without any player.
• The existence of a player who links two lines of play.
• In this aspect we must differentiate when a player occupies this space from his demarcation, or when "it is" his demarcation. In this case the system suffers from a lack of space in relation to the balance between lines, which causes it to be a defensive variant of the basic system.
• The intention to play with more or less defenders, means or forwards in each line of play.
• This intention does not always have a direct relationship with the number of players that make up each of the lines, since for example a player with clear offensive (or defensive) characteristics can be introduced in the media line, which is what will finally give a more offensive or defensive orientation to theteam.

The game system must allow you to manifest:

• Free spaces to take advantage of (demarcations without players).
• Numerical superiority in certain demarcations.
• The relationship of play on the line and between the different lines.
• This relationship implies that the distance between players/lines is maintained between 15 and 20 meters; therefore a basic system will have, as a rule, 3 lines (in addition to the goalkeeper). 

This aspect is important considering the offside rule.

The structure that allows more than three lines is therefore considered a variant of a basic system.

The basic game systems in football-7 are:

• P.2.3.1
• P.3.2.1
• P.3.1.2

In any case, the system that most balances us and allows a faster and more logical adaptation to Football-11 is the P.2.3.1

The basic game systems, at present, in football-11 are:

• P.4.4.2
• P.4.3.3
• P.3.4.3

From these systems, different offensive and defensive variants can be proposed (as we will see later).

These variants of the system are modifications and/or displacements of specific positions/locations, and may be due to: 

• A change of players in relation to their characteristics (more or less defensive/offensive).
• A modification of the number of players that make up one of the lines of play.

We will use one structure or another (game system) in relation to:

• The characteristics of our players.
• The characteristics of the opposite.
• The type of game that manifests itself in the competition in which we participate.
• Exceptionally for the needs to be achieved in the competition.
