Set up your players up in three equal lines. Only the player at the start of line 1 has a ball.
Blue 1 starts the drill with a pass to blue 2 who runs onto the ball and tries to break past the two defenders. If they are unable to find space for the shot they must pass to player 3 who repeats the process.
Drill continues in this way (blue1 - blue2 - blue3 - blue1...)until an opening for the shot has been created.
Every player joins the back of the next line after passing the ball.
The two defenders will need to be communicating and moving quickly to ensure they can keep on the continuous 3v2.
Not only is this good practice for your defenders but it is also excellent practice for your attackers, teaching them to make the right decisions if a defender behaves in certain ways.
