Nigeria beat Bosnia-Herzegovina 1-0 for their first World Cup win since 1998 to leave the Europeans bottom of Group F still without a point from their first World Cup adventure and no longer able to progress to the last-16.
Peter Odemwingie's 29th-minute goal, crashed home at the Pantanal arena after a muscular run and cross by Emmanuel Emenike, liftedNigeria to second place in the group with four points, behind already-qualified Argentina who have six.
Bosnia, beaten 2-1 by the Argentines in their opener, could be forgiven for feeling aggrieved, however, as TV replays showed a disallowed goal by Edin Dzeko after 21 minutes had been incorrectly ruled out for offside and the big striker also hit a post in stoppage time.
Nigeria face Argentina in their final group game on Wednesday, needing a point to guarantee advancing. Third-placed Iran, with one point, take on the Bosnians needing nothing less than a win to stand any chance of pipping Nigeria to the last-16.
