Coach Gernot Rohr has said he is very disappointed the Super Eagles failed to go past the group stage of the 2018 World Cup.
Nigeria fell 2-1 to Argentina in a final Group D match when they needed at least a draw to go through.
“It was a big disappointment because my team gave their best especially in the second half,” Rohr said.
“We were just a few minutes away from qualification.
“But I’m proud of my players.
“We lacked experience, we’re a young team and in four years they will be ready.”
He praised skipper Mikel Obi as a “real leader” and hopes he continues to feature for the national team.
Rohr said he hopes to continue with the team.
He only recently signed a new contract that will expire in 2020.
