6. Bobby and Jack Charlton
Accomplishments: Bobby: 1966 World Cup champion, leading scorer in England and Manchester United history; Jack: 1966 World Cup champion, 1974 Manager of the Year
The Charltons were both starters on the 1966 English national soccer team, the nation's only World Cup champion in its history. They are considered royalty in the soccer-crazed UK, a footballing family akin to the Mannings in the US. Bobby is widely regarded as the greatest player in the history of English football, and he is the all-time leading scorer for both the national team and Manchester United.
Jack has achieved great success as both a player and coach, first winning the World Cup with his brother in 1966 and then winning the Manager of the Year award in 1974 for his work with Middlesbrough. In 1990, he guided Ireland to the country's first World Cup, bringing his ragtag squad all the way to the quarterfinals.
