Liverpool manager, Jurgen Klopp, will be without forwards Mohammed Salah and Roberto Firmino, when they host Barcelona in the second leg of their Champions League semi-final tie on Tuesday.
Salah suffered a head injury during their 3-2 win over Newcastle last weekend, while Firmino is recovering from a muscle tear.
The Reds currently trail the tie 3-0 after the first leg at the Nou Camp last week.
Divock Origi, the substitute who scored the late winner at Newcastle on Saturday, is set to start alongside Daniel Sturridge and regular Sadio Mane up front.
Virgil van Dijk missed full training on Monday, instead undergoing an individual session, due to an ongoing foot problem.
Liverpool provisional squad: Alisson, Alexander-Arnold, Matip, Van Dijk, Robertson, Fabinho, Wijnaldum, Milner, Shaqiri, Oxlade-Chamberlain, Mane, Origi, Mignolet, Gomez, Lovren, Moreno, Henderson, Sturridge, Jones, Brewster, Camacho.
