The Super Eagles will take on Algeria on Sunday in a semi-final clash at the 2019 edition of the continental showpiece.
Speaking ahead of the game, Obuh told Channels TV that to claim the win, Nigeria should not give away the ball cheaply.
He also noted that the team should play the same way they did against the Bafana Bafana and shut out the Fennecs.
In addition, he called on forward Ahmed Musa to be a bit selfish with the ball when he outpaces an opponent.
Obuh counselled him to know when to shoot the ball, cut into the defence or pass to another player.
