LW passes the ball to CB, who has drawn back to the starting position.
Then CB makes a pressure forward and passes to the opposite RB, who makes a cross with RW etc.
It is important that all the players receive the ball while running in and the pressure is put all the way into the defense in order to engage it.
Real defenders can be used.
