"The players gave the Nigerian people a win and now we hope to stay on this course to seal our qualification. Against Argentina, there's no question of us playing for a draw; we'll be playing for the victory," the Eaglets coach said.
A stirring, come from behind game against Germany was followed by a dominant performance against Honduras, although they failed to score more than the one goal that sealed their three points.
Obuh says he is hoping they can marry their passionate, ball playing performance against Honduras with the clinical, goal scoring edge they showed against Germany.
"We made some mistakes in the two games we have played so far. But we scored three goals against Germany and did very well in keeping the ball against Honduras.
"If the boys can do those two things against Argentina, we can get victory."
Obuh and his charges will be happy to return to Bauchi, where they spent some time in preparation ahead of this competition, and will expect to find a lot more support than they did in Abuja, where the fans took a while to get behind them.
Argentina, who are already safely through, are keen to secure the group's top spot although coach Jose Luis Brown has hinted that he may rest a few regulars for Friday's game.
"All the players here are making the same effort, go through the same training sessions and listen to the same talks. Because of that I'll try to give playing time to all of them, especially if certain starters are tired," said the Argentina coach.
Not that that will mean any step down in tempo.
Germany and Honduras play in the group's other game in Abuja.
