Formations
On this page you can create formations per playing style (11x11, 8x8, 5x5, ...) which you can then use in the game preparation and game report. Click the green 'Add' button to create a new formation. You can enter the name and choose which playing style it is for. You can still change the name of a formation afterwards, but not the playing style.
After adding a formation, you can click the blue 'Define formation' button to set up your formation. Depending on which playing style you have chosen, you will see the number of available players at the bottom.
