Klopp, however, has had a full week of preparations and reported no new injury worries after Saturday's thrilling win over Leeds.
Klopp is likely to name the same match-day squad, although Fabinho is set to return to starting line-up at the expense of Naby Keita.
The new recruits must wait for their league debuts for the Blues, with Ziyech still nursing a knee complaint, Chilwell a heel issue and Silva searching for match fitness.
Christian Pulisic is still to shake off a hamstring problem, but striker Timo Werner is fit, having eased past a dead leg picked up at Brighton on Monday.
Liverpool provisional squad: Alisson, Alexander-Arnold, Gomez, Van Dijk, Robertson, Fabinho, Wijnaldum, Henderson, Salah, Firmino, Mane, Adrian, Williams, Matip, Milner, Keita, Jones, Origi, Minamino.
Chelsea provisional squad: Kepa, James, Christensen, Zouma, Alonso, Kante, Jorginho, Havertz, Mount, Loftus-Cheek, Werner, Caballero, Rudiger, Azpilicueta, Kovacic, Barkley, Hudson-Odoi, Abraham, Giroud.
