Nigeria are chasing a record-extending 10th Wafcon title and topped Group B on seven points without conceding a goal.

Yet, as the West Africans turn their attention to their meeting with Zambia on Friday, questions will be raised about their attacking sharpness.

Super Falcons dominated possession against Algeria and created far more chances than their opponents, but were frustrated by a compact and resilient defence which was content to soak up pressure.

Rasheedat Ajibade and Jennifer Echegini offered the most threat from wide areas and midfield runs. Clear-cut chances were rare, and when they came Nigeria could not convert.

The match ended with Nigeria pressing for a late winner, with Echegini sending a curling effort just wide in the 89th minute.

For Algeria, the draw marked a milestone performance as they reach the knockout stages at a Wafcon finals for the first time.

Their progress has been built on a solid defence, having also progressed without conceding a goal.

Ghoutia Karchouni’s winner against Botswana was their only goal of the group stage but has proved enough to extend their stay in Morocco until their quarter-final tie next Saturday.
