The 26-year-old Manchester City striker and his team-mates will attempt to book their place in the semi-finals in Cape Town with the alternative simply not an option.
Tevez told www.clarin.com: "Why not think I can be a champion? Every night, I do. I have a hunger for glory so great that I can not imagine the great sadness there would be without the cup. I could not bear to lose on Saturday."
Tevez's non-stop approach and skill have made him a crowd favourite, and he is desperate to deliver the biggest prize of all for the fans.
He said: "It makes me really happy. It must be my way of playing. I give everything for every ball, and people identify with that.
"Hopefully, with all the boys, we can give them the joy we all hope for."
