Arsenal legend Ian Wright has claimed that Ragnar Klavan remains a weak link for Liverpool following their shaky start to the campaign.
The Reds have shipped 12 goals in the Premier League already this season - only Crystal Palace and West Ham United have conceded more.
Klavan has started just three times in the top flight for Liverpool this term, including in the 5-0 thrashing at the hands of Manchester City at the beginning of September.
Wright insists that the Estonia international has yet to show the quality required to hold down a place at Anfield.
"The defensive errors have been continuing," he told BBC Sport. "Why hasn't [Klopp] addressed the defensive problems? [Joel] Matip is OK but Klavan I'm not sure about."
Klavan joined Liverpool from Augsburg on a three-year deal last summer, costing them around £4.2m to sign.
