Nigeria are aiming for the final of the Under-20 World Cup in Canada
A second-half goal by Brown Ideye lifted Nigeria to a 1-0 victory over Costa Rica
at the U-20 World Cup in Canada on Sunday.
Ideye, who plays for Nigerian club Ocean Boys, headed the ball past Costa Rican goalkeeper Alfonso Quesada in the 75th minute to the delight of the capacity crowd at
Victoria's Royal Athletic Park.
The victory took the Flying Eagles to second in Group F after Japan beat Scotland 3-1 also on Sunday to occupy the top spot.
The goal came just three minutes after the crowd, subdued by the lack of goals, was awakened when a streaker ran on the field.
The naked man ran from one corner of the pitch to the other before a lone security guard attempted to tackle him.
But the streaker managed to tackle the security guard, receiving a roaring applause from the crowd.
He eventually lay down on the field and was hauled off by two security guards.
Nigeria may be without its starting goalkeeper for the rest of the tournament.
Moses Ocheje was injured at the beginning of the second half, when he collided with
teammate Suraj Sodiq while diving for a save.
He had a bleeding nose and had to be taken off on a stretcher.
Ocheje left the stadium 25 minutes later in an ambulance.
He was replaced by backup Olufemi Thomas.
While the Costa Ricans failed to produce many scoring chances, one of their best was in the 25th minute when Ocheje came out to intercept a cross but missed.
The ball fell to Pablo Herrera, but the Costa Rican volleyed it over the Nigerian goal.
