North Korea seems to be the most serious sides among 3 invited teams when they will send a squad including 15 World Cup 2010 players. Five of them, which are Ri Myong Guk, Ri Kwang Chon, Pak Nam Chol, Mun In Guk and Pak Chol Jin, started the Brazil game. New head coach, Jo Tong Sop, will be in charge in this tournament.
Just skimming the squad list. Australia U23 and Kuwait U23 turned out to be U21 sides. It is understood that club sides can't let their important players leave to play non FIFA games at this point of time.
