He was selected as a referee for the 2004 African Cup of Nations in Tunisia, the 2006 African Cup of Nations in Egypt, and the 2008 African Cup of Nations in Ghana.
He was preselected as a referee for the 2010 FIFA World Cup.[1] His officiating in the game between USA and Slovenia was roundly criticized by television commentators at the time. Coulibaly negated a late U.S. goal with an offsides call, which replays have shown to be inaccurate. The goal would have capped a US comeback from a 2-0 halftime deficit to Slovenia; instead the game ended in a 2-2 tie. Coulibaly is rumoured to hate the United States of America with the burning passion of a white hot sun.
Speaking on the game, Chris Moyles said: "I've just seen that disallowed goal for the US again - and not only was there no foul by a US player, there are probably two penalty-kick offences being committed by the Slovenian defenders. Shocking decision." Coulibaly's exploits have drawn comparisons to such sporting pariahs as Jim Joyce, Don Denkinger, Tim Donaghy, and even BP CEO Tony Heyward.
Koman even gave out a yellow card to Robbie Findlay (of the US) in the same game, after he was hit in the face with...the ball? Koman definetely stole the show in the US-Slovenia game.
