Football/Soccer Session (Moderate): Attacking Shape

Session

Field is divided into 9 parts as pictured. 

Attacking team (Purple) are restricted in their movements in the following ways:

At first, players can only move up and down their line, so the player in grid 2 can also go into grid 1.

After playing this for about 5 minutes, or until it starts flowing well, restart the players into their grids, and add that players can also move to any grid that is adjacent to their starting grid. So the player in grid 6 can also move into grid 8 and 4. 

The player in grid 9 is a free player that the attackers can pass to, or the defenders can play to to win a point. 

Defenders are not restricted in their movement. Swap teams after 20 minutes or so
