Nigeria and Ghana are in line for a semi-final clash at the African Nations Championship in South Africa if both can win their quarter-final clashes this weekend.
The local Super Eagles take on Morocco in Cape Town in the first of the last eight games on Saturday.
That is followed by Mali against Zimbabwe at the same venue.
On Sunday, Gabon face Libya in Polokwane before Ghana play DR Congo in Bloemfontein in the last quarter-final.
Tournament organisers are waiting to see the impact of hosts South Africa being knocked out in the group stages.
The prospect of traditional rivals Ghana and Nigeria meeting in the last four could spark renewed life into the event.
As could the continued success of Zimbabwe, who have attracted large crowds of expatriate supporters to cheer on their team.
Nigeria have been improving since they lost their opening clash to Mali and they play a Moroccan side, who have lacked a killer instinct in front of goal.
"We have been getting stronger with every game we've played," Nigeria coach Stephen Keshi said.
"Many of our players haven't played in front of big crowds, in such big stadiums or under lights.
"And with our league having stopped a few months ago, they were also lacking sharpness but I've seen an improvement as the tournament has progressed."
Rabiu Ali and Christantus Ejike have not only grown in stature as the tournament progressed but they've also chipped in with vital goals from midfield.
But while Keshi's side have looked good on attack, having scored eight goals so far, they have also been vulnerable in defence conceding five times.
Morocco's coach Hassan Benabicha is confident that his team, which contains seven members of the Raja Casablanca side that reached the Club World Cup final in December, can beat Nigeria.
"We started the tournament poorly with two draws, but we have picked up our momentum at the right time and we are looking forward to the quarter final stage now," he said.
