Nigeria: The 'Super Eagles' could recall vice-captain Ogenyi Onazi for this one, with Oghenekaro Etebo, the man who put through his own net against Croatia, the most likely to make way. Ahmed Musa may also be involved up front as manager Gernot Rohr looks to add some more creative spark at the sharp end of the pitch.
Iceland: Iceland will be without winger Johann Berg Gudmunsson after he tore his calf against Argentina, with Rurik Gislason likely to be his replacement.
Nigeria boss Gernot Rohr:
"We are ready for this match and we are united, we are working like a team and living like a family.
"You can't always win. They did a good match against Croatia.
"We had 47 percent possession of the ball, we had 14 shots on the goal, they only had 12. They scored two goals but I think we deserved a draw.
"We will not lose this game."
Iceland boss Heimir Hallgrimsson:
"This is a must-win game for Nigeria, and that makes it a little bit psychologically different, they have to win.
"This group is going to be decided in the last minutes,in the last game.
"It’s going to be down to some margins, a set piece, a goal in extra time. This is how this group is going to be played."
