The Spanish striker has now failed to score in his last seven games for the European champions, but Benitez believes that the 28-year-old is still playing well.
"Fernando Torres was great," said Benitez. "He was fantastic for the team. He was working so hard. We needed his effort, his runs, his movement to create the space for the second line.
"Obviously he didn't score but he did a great job. The addition of Demba Ba is something we didn't have before.
"For a month and a half we've had one striker, now we have two and that is great. It means we can manage the games and cope with a little bit more."
