Benfica Possession to Finish

Play starts with a 4v4 centrally plus a joker player who can be used to create a 5v4 when in possession. Both teams must attempt to complete 'x' successful passes before switching the ball out to either of the wide players.  

Once play has been switched to a wide player, 3 players from each team can attack the box creating a 3v3 attacking phase.  Both teams can attack either end of the pitch.
