We play 4:4, with 3 attackers playing in the service of 1 striker.
The goal of the exercise is to free the striker in such a way that she will score. This can be done in many ways, but see what her defender's weakness is and play that out.
You can also take advantage of the attacker's real quality.
Shooter at 6 yards always free after a breakthrough. Coming from deep after a shot from another.
