Create a grid about 35X35. You can adjust the grid larger or smaller depending on the age and skill level of your players.
Create a triangle in the middle of the grid (about 5 yards each side) with training sticks or flags to serve as a goal.
Place a goalkeeper inside the triangle.
Split the group into two even teams of 4v4 or 5v5.
Instruct both teams to attack the three-sided goal.
The Goalkeeper should defend all three sides of the goal.
If a team scores a goal a point is awarded to the team and the ball is live on the other side of the goal.
If the goalkeeper makes a save, he is to distribute the ball into open space away from players.
For a goal to count, the ball must cross through the goal no higher than the top of the flag or training stick.
Only allow a shot on goal after X number of passes.
Play in 1 or 2 touches
Focus on all aspects of the game such as passing, receiving, moving with and without the ball, defending, attacking, and finishing.
The players will have to work together as a team to quickly off-balance the defender and catch the goalkeeper off guard.
