Quote:
Cap-tied is an adjective, used primarily in association football, to describe a player who has represented a national football team in a competitive game and as a result is unable to represent another FIFA-affiliated national team.
A player is 'cap-tied' once he has played in an official competition for the senior national team.[1]
In some instances, players have sought refuge in another country having represented their national team in an official competition. Players such as Maykel Galindo, Lester Moré and Osvaldo Alonso have represented the Cuba national football team and since defected to the United States but are now unable to represent another nation at football.
A player who competes for one nation in a friendly match is not considered cap-tied and may represent another nation in a competitive fixture, should the opportunity present itself. An example of this is Jermaine Jones, who had played three friendlies for Germany in 2008, but started competing for the US in 2010.
With Wikipedia being the be all and end all of all argument because of its accuracy of what it says, I still don't understand why Traore is not eligible to play for the socceroo's if he has only played for a different country at youth level.
