The Dynamo Kiev of Ukraine striker doubled the Eagles lead in the 30th minute after Elderson Echiejile had opened scoring for Nigeria five minutes earlier.
The Nigerian striker admitted after the game that he is expecting a tough AFCON final match on Sunday but believes the first goal will be vital to their triumph.
"My first goal in the tournament has eased off pressure on me," revealed the Dynamo Kiev striker who has formed a deadly partnership with tournament’s joint top scorer, Emmanuel Emenike.
"And Nigerians should expect more from me now but we must maintain that tempo," he added.
Turning his attention back to Sunday's final, Ideye said he would not take the finalist lightly, adding:
"I think it will be a difficult game. You look at the game and some might think it would be an easy game. It's important to be professional and patient and it helps when you get an early goal.
"It's going to be difficult and the first 20 minutes will be really important. There's just one game to win and if we can win them it will be good for everyone."
"The mission is not accomplished yet until we win on Sunday," he concluded.
