The Reds were busy this summer as they brought in a number of new faces, with Brendan Rodgers overhauling his squad following a disappointing campaign last season.
Left back was not a position they strengthened though, with youngster Joe Gomez having come in an impressed in the position despite it not being somewhere he has previously played.
And Lawrenson has questioned where that leaves Alberto Moreno, and why they didn’t look to improve in the position this summer.
“Joe Gomez is playing at left back, and he’ll be a really good player, what does that say about Moreno?” he said to Match of the Day 2 Extra.
“Why haven’t they bought another left back? I really seriously do not understand it of all the players they’ve bought.”
Liverpool waiting on Daniel Sturridge fitness
The former defender has also questioned how the side will fit Daniel Sturridge in once he returns from injury.
The striker missed most of last season through injury and is once again on the treatment table at the beginning of this campaign after undergoing surgery during the summer.
He is a key player in the Liverpool side though, with them sorely missing his goal output. They have brought in Christian Benteke to try and rectify that, but so far the Belgian has been starved of service by his new side.
And Lawrenson says Rodgers may have to drop his preferred 4-3-3 formation as getting Sturridge alongside Benteke will seem them scoring goals.
“Another problem is Benteke, [he] has done okay but there’s scant service at best,” he added.
“You’re almost waiting for Daniel Sturridge to be fit, but if he comes back, how do they play? Brendan Rodgers is very much 4-3-3. If you get Sturridge in the area where Benteke is, you’re going to score goals.”
