Mikel, 32, will lead Nigeria to the 2019 Africa Cup of Nations after missing out the qualification matches for the competition.
And while speaking after the team lost 0-1 to Senegal in a warm-up clash on Sunday, the former Lyn Oslo man said he is not sure of his next move after football.
He, however, hinted that he is not sure that football will be part of what he will go into once he hangs the boot.
“Life after football? I don’t know if I will still be in the game, I have a lot of things going on,” he said.
“I like to do business, I’m a business guy so I don’t know if I will have time to be in the game.
“I love the game but who knows, maybe one day, I might come back to the game but at this point, after football, I am not thinking about being in the game.”
