We are a little country of football and we are playing against a big country of football - so we will have a beautiful game,” said Gernot Rohr, coach of the Niger team."I've seen that the crowd [in Port Elizabeth] was with us and it was a good atmosphere in the stadium and I hope my players will do the same against Ghana."
