Keshi led his side to the last 16 at the 2014 World Cup in Brazil. He coached the national team for three spells, and during one he led Nigeria to the 2013 Nations Cup title in South Africa.
His contract was not renewed following the 2014 world cup, but he returned on a match-by-match basis after the team failed to reach the 2015 Nations Cup finals.
He was then laid off as caretaker coach but reinstated after intervention from Nigeria's then-president Goodluck Jonathan. He left his post for a final time with Nigeria last July.
Keshi was one of only two men ever to win the Africa Cup of Nations both as a player and a coach.
Local media reports say that Keshi died of a heart attack and that he visited hospital last week after complaining of an irregular heartbeat.
