#1 Daniel Arzani (19 years and 152 days)
Australia's Daniel Arzani will be the youngest player at this year's World Cup. At 19 years and 152 days of age, the teenager is only 15 days younger than Mbappe.
After the Iranian born winger had a successful season with Australian A-League side Melbourne City, in which he scored two and assisted three from 16 appearances in the league, the Socceroos manager Bert van Marwijk picked him in the squad that will represent the nation at the World Cup.
Arzani made his senior team debut for Australia in the team's 4-0 win against Czech Republic this past Friday, after he came on as a substitute in the 84th minute of the game.
