Coach Avram Grant's charges' hopes of lifting a fifth continental title were crashed by eventual champions Cameroon, who handed the Black Stars a 2-0 defeat in the semi-finals.
Ghana's ambitions to make up with bronze also proved futile following a 1-0 reversal to Burkina Faso in the third-place playoff on Saturday.
“Though this was not the kind of performance we all expected, I still think the team did not do badly; it was a matter of fortune,” Sannie told Peace FM.
“Luck was not on our side. Even some big African teams with world class players could not excel in the competition.
“DR Congo is a top side in Africa and we were able to beat them.
"The Black Stars could not qualify for the World Cup during my time as a journalist but the team has been consistently at the competition in the past few years.”
Ghana's last title came in 1982, when they beat hosts Libya on penalties in the final.
The quest for a fifth title has proven rather difficult, despite the side making the semi-finals of the last six tournaments.
In 2015, the Black Stars lost to Cote d'Ivoire on penalties in the final.
