This is a fun warm up exercise when teaching attacking patterns of play in a specific formation. In this example I show two teams both in a 4-4-2 Diamond Formation attacking opposite goals. The teams must be aware of each other so not to run into each other during the exercise. This exercise will force players to be aware of the space around them. Feel free to add conditions and variables to the two team shadow play. It usually works better if you have teams make a mandatory of 10 passes before shooting on goal. The coach or coaches can also direct where they want the attack to go. After scoring both teams will jog back to their original starting positions and start the exercise again. Hope you like the drill and try it out this pre-season!
