Make a circle as big or small as you want depending on the range of passing you are looking for. Use football bibs to identify the 3 teams.
-Players work only in their colours.
-The outside players pass the ball to the team mate inside the circle. They receive it and lend it outside to the other player, and so on.
-Encourage players on the outside to constantly move around the perimeter of the circle
-Set the player in the middle a challenge of always trying to keep both team mates in his vision.
Same process as before except when the outside player receives the ball they have a choice.
-Set players a challenge of receiving with one foot ball and playing with the other.
Add a square in the middle. Can players go through the square on their first touch. If there are player in the way (interference), do what you would do in a game, shift the ball and then travel through.
If players want to turn on the outside then the other two still rotate
-Add a target player in the middle square.
-Reds and yellows continue with the same process trying to get through the square. They can dribble their selves or combine with the green player.
-If the defenders win the ball (whites), can they make 3 quick passes
