Former Nigeria international Garba Lawal has charged the three-time African champions to go all out for maximum points against Iceland.
After getting off to a disappointing start in the World Cup - losing 2-0 to Croatia on Saturday, the Super Eagles will hope for a rather positive feat when they take on the Europeans on Friday.
A win against over Heimir Hallgrímsson's side would revive their hopes of progressing from Group D and the Atlanta '96 hero urges the players to 'talk to themselves' and give their all in Volgograd.
"The players know that they need to talk to themselves because they have lost the first game and they need to go all out to win against Iceland," Lawal told Goal.
