Gerrard has failed to return from a groin problem, that has kept him out of action for weeks.
Benitez told the Reds’ official website: “Gerrard won’t travel to Lyon. He has no chance. He is improving but we have to wait.
“He has had an injection but we have to wait two or three days and see how he reacts.”
He continued: “Aquilani had a virus. He trained today but was a little bit weak. Hopefully in two days’ time he will be better.
“Skrtel has no chance. He has a small muscle problem. It’s not too big but he is feeling something.”
He added: “[Daniel] Agger is improving – he will travel and we will then decide. He felt something in his back but it’s much better now. We have to wait and see how he reacts.
“Fabio [Aurelio] is improving but he still has a small problem in his calf, so we will have to wait.
“[David] Ngog is much better, so he could be available.
“[Glen]Johnson is training and working with the physios but he is a doubt at this moment. He will travel to Lyon and we will see.”
