The prospect of a semi-final berth makes Sunday's match against Tunisia "a very special game" for Goran Stevanovic as he prepares Ghana for the quarter-final clash at the 2012 Africa Cup of Nations.

Ghana are chasing a fifth title success with the Black Stars' last Cup success coming in 1982.

The Black Stars must defeat the Carthage Eagles to be able to reach the last four and keep their hopes of reaching the final alive.

"Tomorrow [Sunday's game] is a very special game. The players are motivated, concentrated, they are at hundred percent maximum. I am sure that my players are ready for that,” Stevanovic said at his pre-match conference in Franceville on Saturday.

“We have many reasons to be optimistic because we had a very tough group and finished top. For that we are full of confidence and we believe in ourselves for tomorrow.”

Tunisia will come in much more fresh having rested most of their regular players in the last game but Stevanovic says it would not make much of a difference.

“It’s maybe a small advantage to Tunisia to rest some of the players in the last game."

Ghana will play Tunisia in the last quarter-final game at the Stade de Franceville.
