Nigeria coach Gernot Rohr saw plenty of positives from his side’s 1-0 friendly defeat by the Czech Republic on Wednesday.
He has promised that his players will deliver better performance against Croatia at the World Cup on 16 June.
Despite losing three of their last four warm-up games and drawing the other, Rohr told BBC Sport 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 Argentina, Croatia and Iceland in Group D in Russia.
