Jurgen Klopp is hopeful Naby Keita and Xherdan Shaqiri will feature in Wednesday's friendly against Lyon.
Both players have been absent from preseason training due to injury concerns.
Speaking after Sunday's 3-0 loss to Napoli, Klopp said: "Shaqiri and Keita as well, they trained already with us once, one session. They will come tomorrow and they should be a step further," Klopp said.
"We will see, hopefully they can play a couple of minutes on Wednesday. Five of six back, which is good."
