Speaking to SportingLife, Rohr admitted that Nigeria struggled against Cameroon defensively.
“I will say I agree with you that we had some careless moments against Cameroon that led to the two goals we conceded,” Gernot Rohr said.
“We are working on our defence and I hope to see an improved performance against South Africa. We may have to make a few changes if that will help solve our problem
“We experienced a difficult start to the AFCON after we lost our two full backs to injuries a day to the first game with Burundi and during the game. We had to try out new players and they didn’t disappoint even though they used to take their places.
“We are going to review that area when I sit with my assistant coaches.
“We must find a solution before the game with South Africa because we must make few mistakes against them.
“We are happy that we have our two full backs that got injured back and we shall review if they are in the right condition to stage a return in our next game.”
The Super Eagles is expected to have fullbacks: Jamilu Collins and Shehu Abdullahi, fit for the encounter.
