"Both the senior players and the new ones have one common goal, which is to be part of South Africa 2010," said the 32-year-old forward, who has already played at two FIFA World Cups.
"We missed the last World Cup and we all know how Nigerians felt watching other African teams steal the show in Germany.
"We therefore can't afford another such experience and that's why we're resolved to doing everything to qualify. There is a new belief from the players."
The Super Eagles have been drawn in Group 2 in the final phase of African Zone qualifying, along with Tunisia, Kenya and Mozambique. The round will begin in March.
Kanu also insisted he will be part of the Nigeria squad for their trip to Colombia for a friendly on 19 November, despite reports in the local press to the contrary.
"I will be with the team because I'm a captain that leads by example. And it is not for us as players to pick and choose the matches we want to play," he said.
