Martins and his international colleagues will receive $49,000 each if they lift the cup.
And Nigeria manager Berti Vogts is upbeat about the Super Eagles chances in the competition, which kicks off on January 20.
Vogts: "Nigeria has an over-flowing abundance of players in the best leagues of the world.
"They are showing the right attitude in their clubs, and the NFA has also shown enough support. With all this, I believe that the players can't fail,"
Nigeria, who won the Nations Cup in 1980 and 1994, are drawn in Group B with Ivory Coast, Mali and Benin.
