Stephen Keshi: 'Nigeria were nervous'

Nigeria manager Stephen Keshi has admitted that his players suffered from nerves in their opening World Cup match against Iran.

The Super Eagles dominated for large spells but were unable to make their chances count as they were held to a goalless draw in Curitiba.

"The boys were too nervous and unsettled," he told Optima Live. "You don't do that at this stage.

"It happens in football. We really didn't perform as expected but we have to move on. I wanted a win but must take a draw. We must do better to get a win against Bosnia."

Nigeria will take on Bosnia and Herzegovina in their next Group F fixture on Saturday.
