Offense
One of their attack pattern is the playmaker Izawa passing the ball to the wing Taki, dribbling up the sideline and sending a cross to Kisugi who is scoring (Captain Tsubasa arc, chapter 3, pages 51 to 53). This is their favorite attack pattern (Captain Tsubasa arc, chapter 5, pages 9-10).

Set play
