Nigeria's U-17 national team face their German counterparts on Saturday as they begin the defense of the FIFA U-17 World Cup they won two years ago in South Korea. Nigeria defeated Germany in the semifinals of the 2007 edition before defeating Spain to lift the trophy. The Nigerian team will face a tough task against Germany as they meet in the opening match of the championship at the Abuja National Stadium at 7 p.m. local time on Saturday. Nigeria head coach John Obuh had said that the match with Germany is a must win for his team. 'We know that the Germans are equally good, but we won't be complacent in the first match. That is very important,' he said.
