The Liverpool striker has failed to hit the target at the World Cup, while Fernando Llorente looked more of a goal threat following his introduction against Portugal.
However, del Bosque has backed Torres and is ready to start him in Johannesburg.
He said: "Our striker right now is Fernando. He's played four games, a lot of minutes and will play more. We've got full confidence in him, while we also know that Fernando Llorente brings a lot of qualities too.
"Both need to be full of confidence, both need to know they can be helpful."
