The South Americans are the clear favourites to win Group B with a star-studded squad containing the likes of Lionel Messi, Carlos Tevez and Gonzalo Higuain.
However, Portsmouth striker Kanu does not think the Super Eagles will be intimidated, in what will be their first competitive game under Swedish coach Lars Lagerback.
He told www.kickoff.com: "Argentina have the big-name players and everyone respects them. We also acknowledge that they are good and great players.
"But Argentina also have the same respect for us because they know the quality of our team and know that there is plenty that we can come up with at anytime.
"Yes, it will be tough but I believe we can overcome on the day. It is the World Cup and things do happen."
