3 groups of 8 players.
6 x 5 meter squared areas.
6 players around a 5 meter squared area. 1 touch. The player who loses possession has to replace 1st of 2 defenders, they will then stay in for 2 turns. Anything over 20 passes in considered humiliating for the defenders. Ball can be played on ground or in air. Goalkeepers can be included.
Notes. In the video the groups move after 7 and a half minutes to a new area. This area is the same size. I do not know why they do this. The only reason I can think is to protect the pitch. If you know please leave a comment.
