Nigeria captain Kanu is desperate to play a part at the FIFA World Cup™ after missing the side's opening two defeats in Group B.
The Portsmouth forward has been left on the bench by manager Lars Lagerback but, with the Super Eagles' continued participation resting on Tuesday's match against South Korea, the 33-year-old is keen to be involved.
"That is why I am here. I want to play and I know I can help the team, but it is up to the coach to decide who gets to play," he said. "I am the captain, I can't be unhappy. If I am, then I will be destroying the team.
"For now, we all have to get together and focus on getting the win against Korea and hope that Argentina beat Greece for us to qualify."
Nigeria have contacted their own government and FIFA to register their concern about the death threats received by Sani Kaita after he was sent off in the 2-1 defeat to Greece.
"He has received over 1,000 threats to his email, so we are not taking this lightly," said spokesman Idah Peterside. "We have spoken to the Nigerian Minister of Sports to inform him about the situation, and we are also writing to FIFA to notify them.
"This is just a young man on national service who is trying to do his best. For people to threaten his life is shocking and disappointing. He is shaken, but is getting support from his team-mates and team officials."
Nigeria have a couple of injury worries ahead of their crunch clash against South Korea. Left-back Taye Taiwo is likely to be fit despite sustaining a groin injury against Greece, as is Uwa Echiejile, the substitute who limped off shortly after replacing the Marseille defender.
