Divide your training group into 4 teams and have them stationed and lined up at each of the markers facing the yellow marker.
To start with player A makes a pass to B, player B needs to meet the ball at the yellow marker and holds, then A passes to the Q waiting at the red marker then joins the end of that Q and B moved to the end of the Q at the blue. Then the process starts again from the red Q.
When the two groups get a hang of it get the remaining two teams to play horizontally from orange to pink. Ensure the both are played simultaneously to get the best outcome.
Keep in mind the yellow marker is purely for the image.
Open body shape, first touch, footwork, awareness.
