Goals by Collins Sor and Ahmed Ghali ensured Nigeria went top of Group A of the men’s football event at the on-going competition.
Coach Paul Aigbogun made three changes to the lineup that drew 1-1 with Burkina Faso with Adesina Gata coming in for Success Makanjuola, while Liameed Quadri took the place of Samuel Nnoshiri.
Also, Mathew Yakubu replaced a crocked Detan Ogundare in goal.
Nigeria started brightly and could have taken the lead but for a plethora of missed chances notably by Sor, Ghali and Saeed Jibril.
Sor eventually broke the deadlock in the 27th minute after coolly finishing Saeed Jibril’s pass.
South Africa equalised through Ofentse Mashiane who found space in the Flying Eagles defence in the 55th minute.
Nigeria coach Aigbogun brought on Success Makanjuola and Chinonso Emeka for Jibril and Sor and this helped increase the tempo in the Nigeria attack which resulted in the winning goal.
Ibrahim Abubakar found space to run at the South African defence and whip in a cross which was met by Ghali for his second of the competition and the winner for Nigeria.
The Flying Eagles top the group with four points and will now play hosts Morocco in their last group game on Friday in Rabat.
