Torres has failed to score since his £50million move from Liverpool to Chelsea in January and again drew a blank, although Iniesta believes the former Atletico Madrid man contributed in other ways for Spain's victory over the Czech Republic.
He said: "Fernando is doing really well. It's clear that strikers live to score, but in Granada he gave us plenty of things which people don't see such as hard work, helping out in defence and allowing others the space to play.
"He does work which is not noticed, but it is very fundamental for the team.
"As for the goals, I think it's only a matter of time. He has always scored and he will continue doing so and therefore there are no problems."
