Torres is struggling with a muscle problem he picked up whilst on international duty.
Steven Gerrard has returned and will most likely feature in the game against Lyon.
“Torres is still not ready. Hopefully he will be for the weekend, but not for this game,” said Benitez.
“Steven is fit. He has been training so hopefully he will be available tomorrow.
“It is important as we have had some problems with injuries since the start of the season, so having Gerrard fit is a big boost for us.”
