Nigeria were handed a shocking 1-0 defeat by the Central African Republic in their 2022 Fifa World Cup qualifying fixture on Thursday.
The Super Eagles went into the encounter as favorites on the back of September's wins over Liberia and Cape Verde but the wasteful hosts were punished by the 120th-ranked team on the Fifa rankings in front of their fans.
The three-time African champions failed to convert their dominance at Teslim Balogun Stadium and they were made to pay dearly for it at the death when CAR converted their only shot on target through Karl Namnganda's strike.
In the course of the encounter, Kelechi Iheanacho came very close in the 33rd minute when he turned on his favorite left boot, but his curling effort skipped just wide.
In the second half, the Nigerians continued their dominance. In the 52nd minute Osimhen was denied by the bar after striking low inside the box while substitute Taiwo Awoniyi saw his follow up effort deflected for a corner.
CAR had a rare chance in the 64th minute but Nigerian keeper Francis Uzoho who had been idle all game made a decisive save to deny Namnganda with his feet.
Nigeria continued to pile the pressure with Osimhen having two chances, first heading just wide from a cross while in the 84th minute, he swung a volley inches over.
Off a counter, Nigeria were made to pay. Namnganda was off on a counter and battled two defenders, Leon Balogun falling on his way before he fired low past the keeper at the stroke of 90 minutes.
From the result, Nigeria remains top of Group C with six points while CAR climb up to third with four points, same as second placed Cape Verde who had earlier come from behind to beat Liberia 2-1.
With Cape Verde winning 2-1 in Liberia, the Super Eagles retain their leadership of Group C, but must avoid any slip-up against Les Fauves in the Match-day 4 encounter at the Stade Japoma de Douala in Cameroon.
