Courtesy of American sports journalist Doug Chapman, here is a list of former Addicks going to the World Cup:
Darren Bent - England
Jonathan Spector - USA
Madjid Bougherra - Algeria
Stephane Andersen - Denmark
Dennis Rommedahl - Denmark
One might also add 'Judas' Defoe considering that he was poached from the youth team. Danny Shittu (Nigeria) was also in the youth set up.
