Nigeria goalkeeper Daniel Akpeyi will miss Friday's World Cup qualifier against Cameroon in Uyo with injury, coach Gernot Rohr said at the team's press conference held at the Ibom Meridien Hotel on Wednesday.
"We are under pressure to beat Nigeria as we are four points behind the leaders, so losing tomorrow will dent our aspiration of going to the World Cup".
Hugo Broos, say the Indomitable Lions, having played at the Confederation Cup in Russian Federation, is more experienced than the Super Eagles of Nigeria.
The Indomitable Lions and Nigeria's Super Eagle, are set to clash in a double header with the first leg in Uyo on Friday, September 1 and the return leg in Yaoundé on Monday, September 4.
Furthermore, in their last meeting, in a friendly, the Super Eagles won 3-0, in a convincing display that may still be hurting the Indomitable Lions' egos.
He said: "We have prepared very well and the team is in high spirit, ready to do their best".
"If we get positive results at home and away against Algeria, I think the gap won't be that much".
"This is a very crucial match and the players know so".
Nigeria have been winners 10 times, in 20 previous encounters, with Cameroon winning four times and six matches drawn. "A win is a win, we want to win (against Cameroon), and that will give us an added advantage in the qualifiers", stated the former Chelsea star, who now plies his trade in China.
On his part, Rohr explained that his men know they have a big game on their hands.
Mikel Obi insists that even though he has played in a World Cup before, he remains highly motivated to go again.
Mikel Obi, Simon, Ighalo and Echiejile are in the Nigerian squad that will seek a repeat scoreline on Friday.
