His place has since been taken by Carl Ikeme, who features for English Championship side Wolverhampton Wanderers.
“I live in France and I know Enyeama. He’s a good player and I do not know why he is no longer playing for Nigeria,” said the Franco-German coach.
“We have spoken and perhaps I hope to meet him soon because we need our best players for us to have the best chance to qualify for the World Cup.”
Nigeria are drawn in a tough qualifying group for Russia 2018 with Algeria, Cameroon and Zambia.
They begin their qualifying campaign on October 3 in Zambia, before the host Algeria the following month.
“It’s my mission to qualify Nigeria to Russia 2018,” he said.
“Nigeria have the best players in Africa and I have the German mentality to bring good organisation and discipline to this team.”
