"Four players, Ali Karimi, 31; the captain against South Korea, Mehdi Mahdavikia, 32; Hosein Ka’abi, 24; and Vahid Hashemian, 32 wore either green wristbands or armbands during the first half of the match....The players were told to remove the wristbands at halftime because FIFA, the sport’s world governing body, prohibits any political displays and because the bands were not part of their uniforms...The gesture by the players drew worldwide attention and comment. In addition to being barred for life by Iran’s soccer officials, the four players have been forbidden to give interviews to the news media." NYT
"Ahmadinejad, a known football fan, has taken a close interest in the sport's affairs. In 2006 Iran was banned from international competition by the world governing body Fifa after claims of improper interference by his government. The ban was later lifted.
This year the national team coach Ali Daei was sacked, reportedly on Ahmadinejad's orders, after a 2-1 home defeat by Saudi Arabia." The Guardian
