The recommended playing formation is 1-4-3-3.
In the 1-4-3-3 formation there are 3 lines with a balanced spread of players over the pitch ('triangles' of players) which creates good conditions for:
- effective positioning play
- playing out
- combination football / short passing game
- creative and varied attacking play using the width of the field
- early disturbing and pressuring after losing possession
For youth players, the positions and the basic tasks are logical and recognizable, which makes learning to play as a team easier to develop.
The Optus SSF formats 7 v 7 (1-3-3) and 9 v 9 (1-3-2-3) lead up to the 1-4-3-3 formation in a logical and methodical manner.
