USA coach Bob Bradley says everyone was delighted to welcome President Bill Clinton into the dressing room after their shock win over Algeria.
Clinton has been in South Africa following the USA's successful World Cup campaign.
Bradley said: "President Clinton, we also met him at the White House, he is a very charismatic man. He makes people feel right at home. That day before President Obama came out (at the White House), he had already shaken people's hands, started little conversations.
"In this moment, he came in after the game when obviously everyone was so excited and we were very honored that he could share that moment with us."
