The United States football coach Bob Bradley has called for players who feigned injury to be banned for a "good number of games", saying he would be ashamed to be associated with such blatant cheating.
Bradley, who describes himself as an "old school" manager, says he hates seeing players getting away with ruining another player's match.
He says it's the easiest thing to clean up and seeing Kaka get sent off, I think that's too bad for the game because he's a great player.
Brazil's Kaka, one of the highest profile players at the World Cup, was sent off against the Ivory Coast for allegedly elbowing Abdelkader Keita, although replays showed the Ivorian was clearly exaggerating the impact.
Bradley says he'd be ashamed if he was the one doing it.
