Nigeria Dream Team VI beat Japan 5-4 in their first Group game of the football event of Rio 2016 Olympic Games.
Due to a series of delays, the Dream Team VI landed in Manaus just few hours to the kick-off and had little time to rest and prepare for the game.
The game came alive from the first minute as Royota Ohshima forced an early save from the Nigerian goalkeeper, Emmanuel Daniel from a volley.
It took Nigeria just two minutes to score the first goal of the game through forward Sadiq Umar.
Imoh Ezekiel dribbled brilliantly from the right before unleashing a shot that was spilled by the Japanese goalkeeper and Umar was in the right place for a simple tap in.
Japan leveled immediately three minutes later via a penalty which was given after Stanley Amuzie fouled Shoya Nakajima in the box.
