Teams will use the 4-3-3 formation, either in its 4-3-3-1 or 4-1-2-3 variations. Teams in the advanced stag(U15 onwards ) can also use a 4-4-2 formation with a diamond in the middle. This system (4-4-2 diamond) provides more space in the wide areas of the field for the outside backs to move forward and join the attack.
