This is an excellent drill to help teach passing. The basic shape in soccer is a triangle. Actually as you think about are younger teams, three is a base number. In Under-6 soccer, we play 3v3. In Under-8 and Under-10, we play 6v6. In Spring Soccer, our U-10 teams move to 9v9. Are we seeing a pattern?
For this drill, set up a triangle using cones. In each triangle, assign up to four players. The player passes the ball to their team mate and then follows their pass. The player that receives the pass, then passes to the next player and also follows the pass. So not only is the ball in motion, but also the players.
Players should work on accurate push passes to their team mates.
