The Ravens will take on Matsatsantsa, in what is expected to be a pulsating CAF Confederation Cup final second leg, at the Lucas Moripe Stadium at 20h15 this evening.
The Congolese giants come into the tie with a slight advantage, having won the first leg tie 2-1 at the Stade TP Mazembe last Sunday.
History might be on the hosts' side, though, as the last time the two sides met in Tshwane, their group stage encounter ended in a 0-0 stalemate on June 20.
However, Kalaba is admanat the stakes are higher this time around and assures his team will put more effort into trying to score and ensure they lift the cup at the end of the match.
"This is a different ball game [as compared to the group match], because this game is about goals. The team that will have the chance to score must score," said Kalaba.
"I think there's a difference between this game and the previous one, because before we were playing for qualification [through the group]," he added.
"This game is about the cup, and the cup [opportunity] is not always going to come tomorrow or on another day, it only comes once.
"The whole team will put more effort to take the cup. It will be down to both teams, and after 90 minutes the final score will determine the result."
