Coach Stephen Keshi feels his Nigeria side delivered a victory for all of Africa after Peter Odemwingie's goal put the Super Eagles on the brink of reaching the World Cup knockout stages.
The Stoke striker's smart first-half finish decided a 1-0 win over Bosnia-Herzegovina in Cuiaba and the result, while eliminating the Europeans from the tournament, sees Nigeria well-placed to progress from Group F.
A point from Wednesday's meeting with Argentina - 1-0 winners over Iran earlier on Saturday thanks to Lionel Messi's late goal - would be enough for second place. Victory would see Nigeria go one better and grab top spot.
And with West African neighbours Ivory Coast and Ghana also making a big impression in Brazil, Nigeria boss Keshi is determined to make sure his team are among the continent's representatives in the last 16.
He told FIFA.com: "Everybody is happy in West Africa; Ghana got their result (2-2 draw with Germany) and we won.
"It's good for the continent.
"The fighting spirit we showed was good. I never thought that we wouldn't make the round of 16. I have the players.
"But look at Iran today, if it was not for Lionel Messi. We need to work hard for the game against Argentina."
Match-winner Odemwingie, who tucked away Emmanuel Emenike's cross shortly before the half-hour mark, credited his colleagues for sticking together to secure all three vital points at the Arena Pantanal.
"The goal means a lot to me," he said. "But the win was down to 90 minutes of concentration and effort from my team-mates.
"The most important thing today was the character. We even enjoyed defending together.
"I don't know anyone who doesn't love this country. Playing for my fatherland is an honour and a pleasure.
"I didn't expect to score a winner in such an important game, I'm very happy.
"But this was a point the team earned. Right now I'm so high on our team's performance."
