Stephen Keshi: 'We must address problems in attack'

Nigeria manager Stephen Keshi has admitted that his side's struggle to find the net is a concern ahead of their meeting with Bosnia-Herzegovina on Saturday night.

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.
