Virgil van Dijk and Jeremy Jacquet are their only fit options after Joe Gomez picked up an injury during the 4-2 pre-season win over Sunderland.
Van Dijk is not expected to join Liverpool’s pre-season squad until they return from their tour of the US this month.
Jacquet, meanwhile, has only just returned from a serious shoulder injury and is still working his way back to full fitness.
Giovanni Leoni is recovering from an ACL tear and will miss the start of the Premier League season.
Now, according to Fabrizio Romano, Liverpool have decided to address their defensive injury crisis with a loan move for Barcelona’s Araujo.

Liverpool are next in action against Monaco at Anfield on 9 August.
