Former Arsenal defender Martin Keown thinks that Liverpool have problems at the back after they went down 2-0 away to Burnley, noting that Ragnar Klavan struggled at Turf Moor.
Burnley took the lead in just the second minute through Sam Vokes, before Andre Gray then made it 2-0 by striking in the 37th minute.
Liverpool dominated possession throughout, but struggled to carve Burnley open to create clear cut chances and suffered defeat, not even being able to breach the Clarets' backline once.
The Reds conceded three goals against Arsenal last weekend to go with the two at Burnley and Keown is worried.
He said on the BBC's Final Score programme: "Liverpool look concerning at the back.

"Jurgen Klopp is not a miracle worker. They are shipping goals and need to sort that out", Keown added.
The former Arsenal defender also took aim at Klavan, brought in from FC Augsburg in the summer to replace the departed Martin Skrtel, feeling the Estonia international struggled badly.
"He's moved Skrtel on and brought Klavan in – and he was all over the place today", he explained.
"[Dejan] Lovren at times made some important tackles, but where is the leader in there?
"[Alberto] Moreno was left on the bench and there are issues for them, so they have to sort that out."
Next up for Liverpool is EFL Cup action with a trip to take on Championship side Burton Albion.
Their next Premier League clash is a tough looking trip to Tottenham Hotspur next Saturday.
