Super Eagles Coach Gernot Rohr said he made sacrifices in his new contract with Nigeria in order to guide the country to a fourth Africa Cup of Nations triumph.
The Super Eagles have won the Africa Cup of Nations three times -- in 1980, 1994 and 2013.
"We have a good team, we're now number three in Africa.
Rohr led Nigeria to third place at last year's Africa Cup of Nations Finals in Egypt, where they lost 2-1 to eventual champions Algeria in the semi-finals after conceding a stoppage-time goal.
His team tops their qualifying group for the 2021 Africa Cup of Nations slated for Cameroon with six points after winning their first two games against second-placed Benin and Lesotho, who are third.
