After beginning their World Cup campaign with an uninspiring goalless draw against Iran on Monday, Keshi believes that finding top form in attack is the biggest problem for a group of players who scored just 11 times in qualifying.
"Yes, we need to work on scoring goals," the 52-year-old told members of the media. "But it is not only the attack that needs work - we also have to work on other departments too.
"But sometimes anxiety comes up on these boys and they want to just score. Otherwise, I think they played well against Iran, it's just the finishing that is the problem."
Both sides will be looking for their first win in Group F after Argentina eased past Bosnia-Herzegovina on Monday.
