Torres has had four weeks off after taking part in the Confederations Cup with Spain.
"I don't remember the last time I had four weeks off in a summer so it was great and now I am fully prepared for the season, which should be a good one for all of us," said the striker.
"Some of us are behind but we are trying to get fit as soon as possible. It's difficult for us guys from the Confederations Cup to fit into the team now because the other guys have had 22 days more than us."
