Two coaches work in each zone. Different techniques are developed in each zone. Five players per group. Four minutes work in each zone. Half-time break for drinks etc.
Repeat exercises for two minutes each.
Finish after one hour, choose one technique to be practised for 'homework' and send home with parents. Make players aware of what you are doing and stick with it. If a player's instinct is to pass rather than to shoot, then no amount of instruction during the game from the sideline will change this. Only sustained, constructive coaching will work. Then you will have helped develop new instincts.
