It is believed Finidi took the decision on Saturday, days after the Nigeria Football Federation, NFF, announced moves to bring in a foreign technical adviser.
His exit was confirmed by former Eagles media officer, Toyin Ibitoye, on his X account.
Ibitoye wrote: “News just in: Finidi George @FinidiGeorge_FG has resigned from his @NGSuperEagles manager position.”
Finidi was only appointed on April 29, 2024, to replace Jose Peseiro, whose contract expired in February.
During his very brief tenure, the former Enyimba boss oversaw a 1-1 draw with South Africa and a 2-1 defeat to Benin Republic, both in the 2026 World Cup qualifying series.
