Ghana remain winless at the Africa Cup of Nations after they were held to a 0-0 draw by Group F leaders Cameroon at the Ismailia Stadium on Saturday.Kwesi Appiah’s side could only manage a 2-2 draw against Benin in their opening game and they were frustrated again versus a Cameroon side who move on to four points at the group’s summit.Ghana came agonisingly close to sealing all three points in the closing stages when substitute Owusu Kwabena’s powerful drive crashed back off the crossbar.

Kwabena came so close to securing a precious win three minutes from time, picking up Jean-Armel Kana-Biyik’s loose ball on the halfway line and charging forward before thundering an effort against Onana’s crossbar, but, in truth, a winner for either side would have been scarcely deserved.
