Virgil van Dijk is due to see a specialist as he fears his hamstring injury is worse than originally thought.
The centre-back was replaced at half-time in a 3–1 loss to Brentford.
Van Dijk picked up a hamstring strain in the first half and had an initial consultation with his specialist.
Liverpool are awaiting a decision on the extent of the injury and whether he will be out for longer, reports The Athletic.
When asked about Van Dijk’s injury after the clash with Bees, Jürgen Klopp hoped it would not be too serious.
He said, “Virgil felt a little muscle, but he said he was fine and he’s very sensitive about these things.”
He had this feeling of “I don’t want to miss an opportunity.” The physiotherapist seemed very happy when he said he didn’t want to take the risk. It wasn’t an injury, just a feeling of strength. ”
Meanwhile, the Reds are set to return centre-back Billy Coumetio, who has been loaned out to Rapid Vienna.
Klopp also has Joel Matip, Ibrahima Konate, Joe Gomez and Nat Phillips and is unlikely to sign a defender this month.
Instead, Liverpool have secured striker Cody Gakpo and are said to be exploring the possibility of signing Wolves midfielder Mateus Nunes.
Liverpool are reportedly set to sign the Portuguese player for €50m, but manager Julen Lopetegui has ruled out leaving the club.
And Klopp hinted that spending would be capped after Liverpool suggested ‘we can’t play Monopoly’.
