Chelsea's Victor Moses converted two late penalties to give the Eagles a win over Ethiopia and book a quarterfinal showdown with Cote d’Ivoire.
Ethiopia's stinginess frustrated the Super Eagles, who will be shorthanded in the quarterfinal after Fegor Ogude collected his second yellow card of the first round midway through the second half to rule him out of the elimination match.
The Eagles' perseverance paid off in the 78th minute, when Moses was scythed down in the box for the penalty, which he took and calmly rolled to the left side of Sisay for the Eagles to take the 1-0 lead.
Three minutes later, Vincent Enyeama made a great save off a Seid Saladin header that seemed destined to be the equalizer. John Mikel Obi was given a yellow card for a foul on the edge of the box, but on the ensuing breakaway, Moses rounded goalkeeper Sisay Bancha, who brought him down for another penalty kick.
Ethiopia had to convert Adane Girma into an emergency goalkeeper to face Moses, who kicked to the makeshift keeper’s right to record his second goal of the game and of the tournament and put away the result.
Five Nigerian players were a caution away from missing the quarterfinal but only Ogude will now miss the confrontation with the Didier Drogba-led Cote d’Ivoire on Sunday in Rustenburg.
