Graham Arnold, the 62-year-old Australian coach, is facing the biggest challenge of his coaching career as he aims to guide Iraq to their first World Cup in 40 years. Arnold, who previously worked with Australia, would become the first Australian coach to qualify for a men's World Cup with two different nations if Iraq beats Bolivia in Monterrey, Mexico. He does not speak Arabic but understands the enormity of the challenge for Iraq. The team's absence from the World Cup has been attributed to conflict and the interference of Saddam Hussein's son Uday, who was accused of torturing footballers.
