One is Africa's leading nation with vast experience of international competition, while the other is a 138th-ranked island with a population of just 178,000.
Those two statistics alone mean there should be a vast gulf in class between the two sides on Monday, as they contest their opening Confederations Cup fixture.
But with Nigeria troubled by a dispute between the squad and the nation's football federation, Tahiti will hope to pull of one of the great shocks of international football.
It will be buoyed by the fact the Super Eagles are without Victor Moses, Emmanuel Emenike, Kalu Uche and Ogenyi Onazi through injury, while hoping center back Nicollas Vallar recovers from an ankle injury in time to aid their cause.
