Gernot Rohr, the coach of Nigeria had lamented that soccer fan were withdrawing their support for the Super Eagles ahead of 2018 World Cup.
Nigerians soccer have been grumbling since the squad lost three of their last four warm up games and drawing the other.
However, Rohr had promised that his players will deliver better performance against Croatia at the World Cup on June 16.
“We lost again another match, everybody is angry about it and this anger is positive,” Rohr told BBC Sport yesterday.
“After we won against Argentina in a friendly (in November), everyone talked about us reaching the semi-final and now 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.”
But, Rohr gave an update on Leicester midfielder, Wilfred Ndidi, who had been out since April with a hamstring injury.
“We had some positive lessons especially with the return of Ndidi. He has not played for two months.” Rohr also said.
“It was very important to see him playing again. Normally, he should play 70 minutes but could play 90 minutes which is very good.
“The medical team did a great job. Now Ndidi will be fit for the World Cup.”
