Former Super Eagles handler, Stephen Okechukwu Chinedu Keshi died suddenly in the early hours of Wednesday in Benin City, Edo state.
Keshi, a truly Nigerian football icon, was billed to travel back to his base in the United States later Wednesday when he suffered a suspected heart attack a little after midnight.
The former international football player and coach had lost his wife of 35 years, Kate, last year after a prolonged battle with cancer.
His death was confirmed from a member of his family as well as one of his close associates.
According to a friend and a former member of his backroom staff when he was in charge of the national team a couple of years ago: "He (Keshi) was hail and hearty. I still spoke with him for a very long time on Tuesday. Throughout our long conversation, not once did he complain of anything illness."
However, another friend said: "He was not ill at all, never showed any signs of illness, but we suspect he never got over the death of his wife
