Nigeria scored twice in four minutes to beat a stubborn Zimbabwe 2-0 in the African Nations Cup to stay on course for the quarter-finals.
Midfielder Christian Obodo headed the Super Eagles in front after 56 minutes and substitute John Obi Mikel added the second with a scorching drive four minutes later for his first international goal.
Nigeria top Group D with six points from two games but still need a point against Senegal on Tuesday to guarantee qualification.
Zimbabwe, who have lost both their group games, still have a mathematical chance of going through if they beat Ghana.
