Nigeria has been assured at least a silver medal in men's football after the national team beat Belgium to 4-1 advance into the finals. Nigeria took the lead through Olubayo Adefemi , while Chinedu Ogbuke Obasi scored the next 2 goals, and Chibuzor Okonkwo hit the forth. Laurent Ciman scored the only goal for Belgium. On the other hand, Brazil and former champion Argentina will be playing each other to claim another place in the finals. So, it's Nigeria versus either Brazil or Argentina for the gold medal.
