Yes they were
Yes Nigeria are in the 2010 world cup.
Nigeria did not pass the first round in the world cup.
2002 FIFA World Cup
No Nigeria have not won a world cup, or for that matter no country from Africa have ever won the world cup. WTH ! To the comment above mine, Nigeria has in fact won the World cup 2 times in a row, the first in 1984 and the second in 1988.
In order to find out if Nigeria is in soccer 2014 which is the World Cup that will be held in Brazil, one has to wait for the World cup qualifier matches to end. Nigeria is pooled alongside Kenya, Malawi and Namibia for the World Cup qualifying matches.
Nigeria first qualified for the World Cup in 1994. More of Nigeria's statistics are shown on the related link.
