In this small-sided game players are crossing into areas that attackers can shoot at goal from. Look for good build up play into the attackers. In the progression the 4 neutral players link up with the team in possession creating overloads
Play out from the back into the full-backs
Build up play from defence into midfield to create space to pass the ball to the wide neutral players
Good technique to cross the ball with different angles and different heights
Technique to cross should be supporting foot next to ball, use toe/instep to cross the ball with height and distance
Defending players should be pressing the ball and trying to block crosses
