Coach Imama Amapakabo has praised the character of the home-based Super Eagles after they overcame a difficult qualifier to advance to the group stage of the WAFU Cup of Nations.
Nigeria needed late second half goals by Osas Okoro and substitute Peter Eneji to beat Sierra Leone 2-0 to book their passage to the group stage of the sub-regional tournament.
In group A Nigeria is drawn against hosts Ghana, Mali and Guinea.
The Eagles face the Black Stars of Ghana on Thursday in their first opening group game.
Imama says the team hope to be a lot more settled by the time of this clash between the two perennial rivals.
