Iranian born Australian winger, Daniel Arzani will be the youngest player at this year's World Cup. At 19 years, the teenager is only 15 days younger than Mbappe and is widely considered to be a promising prospect for the Socceroos.

The Socceroos manager Bert van Marwijk picked him in the squad for the World Cup after judging the winger on his season with the A-League side Melbourne City. Despite bagging just 2 goals and 3 assists to his name in the league, Arzani's end product must improve but he has been given the chance to showcase his talent on the grandest stage by the former Dutch manager.

Arzani made his senior team debut for Australia in the team's 4-0 win against the Czech Republic this past Friday, after he came on as a substitute in the 84th minute of the game.
