The centre-half is back in full training after recovering from a muscle injury sustained in January.
Darwin Nunez, meanwhile, will continue to be assessed for the shoulder issue that forced him to sit out the weekend's draw at Crystal Palace.
Joe Gomez, Thiago Alcantara and Luis Diaz remain sidelined for the Reds.
Offering an update ahead of Wednesday's fixture with Wolves, Klopp told Liverpoolfc.com: "Darwin trained yesterday with us. Let's see if it's good enough for being part of the squad.
"Ibou trained now completely normal. Should be absolutely OK for the squad at least. Joe is injured.
"Lucho [is] looking good. I just watched him now training with the rehab guys and that looks really good – but he was not in team training yet, so that will take a while. And Thiago, in the moment, is doing his rehab."
