The Eagles are now topping the group on 6 points, four points above Cameroon, and five above Algeria and Zambia.

Pinnick, in a statement released by Demola Olajire, Head of Communication, NFF, on Thursday, urged the team to commit heart, soul and spirit to the match. "We have experience in the team now", he said.
He said "German machine" Leon Balogun has returned to add aggression to the heart of the back four after injury kept him out in June, while "natural leader" skipper Mikel Obi and "our best striker" Victor Moses are also back in the fold. "Against Cameroon, all of us will play for him", Rohr told media. To get to Russian Federation, we need to beat Cameroun.
"They have always given us problems beating them", he admitted.
"Those three points are very important to our FIFA World Cup qualification campaign, and I am confident we will get them", he said.
On his part, Rohr explained that his men know they have a big game on their hands.
They will be rugged as usual, tight and well organised at the back with AFCON 2017 MVP Christian Bassogog, Vincent Aboubakar and Fabrice Olinga their major threats in attack.
