Burkina faso, Mali, Nigeria and Ghana are the semi finalist. This leaves the title wide open after tournament favourites Ivory Coast crushed out.
Ivory Coast were knocked out of the Afcon after some great display on route to the quarters. The Ivorians started the match very chilled out and were stunned by Nigeria 's desire and industry. The Nigerians made all the early running and created most of the chances. They were rewarded for all their hard work with a stunning opener from Emenike just before the break.
Ivory Coast seems to wake up from their stupor in the second half and went a gear up. The pressure paid off with an equaliser 5 minutes after the break. Newcastle 's Cheik Tiote got on the end of a Didier Drogba free kick to head home.
Nigeria continued to press forward despite the equaliser and Mba scored the winner 12 minutes from time, sending a star studded Elephants team crushing out.
The Ivorians are being labelled chokers already.
Meanwhile Burkina Faso beat Togo 1-0 while Ghana beat Cape Verde 2-0. The hosts South Africa lost out to last year's semi finalists Mali on penalties.
