They need a win to end a 38-year wait since their last participation at the continental spectacle.
“This is the time to be a man, this is their chance to make history," Amuneke was quoted as saying by Concisenews.
“The fans will come out to cheer them to victory. I wish I could play this match, but unfortunately, I cannot.
“I will be shouting and directing them (from the sidelines) instead.”
The former Barcelona forward also described the match as the most important in Tanzania’s recent history and also called on the nation to rally behind his side.
"This will be the most important match for Tanzania in recent times," he said while addressing the media in Dar es Salaam.
"It will be a match of moments. I call for calmness because every side will get their chances.
"I call upon the Tanzanians to get behind the team at all times. Even when we are low, we shall rise up. I have the hope that we shall win the game."
Amunike won the Afcon with the Super Eagles as a player in 1994. He will look to also end Tanzania's absence at the finals in Egypt this summer.
