And the Nigerian Football Federation complied with Fifa's request for a written guarantee that the game would go ahead safely.
Keshi has now followed that up with comments on UK-based African TV show,
Vox Africa's Sports360
, saying: "I think the coach of Malawi is crazy.
"If he wants to talk to Fifa, he should go back to Belgium. He is not an African person, he is a white dude, he should go back to Belgium," Keshi said.
"I have never used any words like these to any coach. He has no right, who is he?
"All other countries play in Calabar. Calabar is one of the safest places in Nigeria... He is mad. I wish I could say it to his face."
Saintfiet, who married a Zimbabwean earlier this year, told BBC Sport he is "shocked" by Keshi's comments and he believes the former Nigeria captain's words could also lead to trouble at the qualifier.
