Play starts with a 3v2 rondo on one side of the pitch. After 'x' amount of successful passes, the team in possession can switch to the opposite rondo grid through the defensive midfielder player.   

If the 2 players out of possession win the ball, they must attempt to score into either of the mini goals.  

As a progression, you can add an attacking phase after every successful switch of play where the possession team will attack in a 3v3 phase.
