After the disappointing barren draw against Rwanda on Monday, the Coach Salisu Yusuf-tutored side can not afford further slips against the table toppers, Libya.
Sunday Falaye scored the only goal of the game against Libya to help the Super Eagles of Nigeria secure their first win at the ongoing African Nations Championship (CHAN) in Morocco.
The first 45 minutes at Grand Stage de Tanger was a drab affair.
Rwanda will play the last game against Libya on Tuesday looking for a win or a draw to reach the quarter-finals while Nigeria will play against Equatorial Guinea.
Constant fouling meant the match never developed a rhythm and neither side created a clearcut scoring opportunity until Faleye netted 11 minutes from time.More news: Amazon Increases Monthly Prime Membership Rate to $12.99

Immediately after the hour mark, Yusuf brought on Ibrahim Mustapha for the largely ineffective Okpotu but it was the Mediterranean Knights that responded via Abdelsalam Alaqoub.
Rayon Sports center defender Thierry Manzi converted a wonderful corner taken by Djihad Bizimana in the 66th minute to put Amavubi in the lead.
Salisu Yusuf's men dominated the game but had to wait until the 79th minute for Sunday Felaye to score the victor from an Osas Okoro corner.
Libya and Nigeria were locked at 0-0 during the half-time break.
As a result, the Super Eagles climb up to the top of the group standings, while the Mediterranean Knights move down to second place.
