Well from the looks of things Nigerian still got a long way to go and a tough road to ahead to qualify in the game currently they have got fourth point ahead of south Africa to qualify Nigeria will likely need to wins aleast five matches which this will be an daunting task, I guess their match will be against Zimbabwe on March 25 which will be a most to win their by all means, the team poor start to qualify with three draws and one loss in their fourth rounds and this has kept them in an difficult position.
At this point of the group stage South Africa is in the least of Nigeria worries because SA is one team that have already qualified even with a draw in their next fixture, meanwhile Nigeria is just with 6 points presently after their 2:0 win against Rwanda. At the moment it is mathematically possible for Nigeria to qualify, so they've to focus on winning their next game and see what the outcome for next fixture becomes for teams like Benin Republic who are in second place and Rwanda third followed by Nigeria in fourth, and then Zimbabwe the bottom owners.
