As many pairs as you have players. Start with blue playing to red and then closing down the space to protect their cone. Start with passive attacking just working on body shape of the defender. Then make it a game where to score the attacker must be able to hit the cone with the ball after beating the defender.
Coach the defender;
1) Fast, slow, sideways and low. when closing down the attacker.
2) When we are starting with passive attacking look for the defender to stay in a delay position not trying to win the ball. When we move to the game look for the defender to find the right moment to get the ball. A bad touch, attackers eyes down, attacker has ball close to defenders body.
