The former Atletico Madrid man has had the chances but has not been able to make the most of them.
Nevertheless, Del Bosque is still pleased with what Torres has contributed to Spain's qualification for the last 16, even it if has not been goals.
"What's important is that he's played in the three games and has progressed in his preparation," Del Bosque said.
"He's a player who even though he hasn't scored goals he benefits us as someone who makes it hard for opposing defences and who is always a threat to the other team. He's a very dangerous player."
Torres himself admits he is not yet back to full fitness, telling Radio Marca: "I'm still lacking a bit, it's not easy to return after an operation.
"I think I'm still a little away from being 100%, although I'm close."
