Nigeria coach Gernot Rohr saw many positive aspects of his team’s friendly defeat 1-0 against the Czech Republic on Wednesday.
He has promised that his players will offer a better performance against Croatia in the World Cup on June 16.
Despite losing three of his last four preparation matches and taking the other out, Rohr told BBC Sport that he is focusing on the World Cup:
We lost again another match, everybody is angry about it and this anger is positive.
After we won against Argentina in a friendly [in November], everyone talked about us reaching the semi-final and the results now has humbled those voices.
Because we need humility, it is helping us. We also need solidarity and hard work. Everybody understands this after the defeat to Czech Republic.
Nigeria will face Croatia, Argentina, and Iceland in Group D in Russia 2018.
