Ireland head coach Andy Farrell goes up against Australia counterpart Joe Schmidt once again at the Aviva Stadium on Saturday evening. Gain-line theory powered the Wallabies’ attack for 90 years. Despite Suaalii’s obvious skills, Australia have continuously failed to involve him in any set-play attack. Schmidt’s attacking set-play plan has to be: “Give the ball to Joseph.”Both teams are out of form. Following a promising run of form earlier in the year, Joe Schmidt's Australia have lost their way recently.
