Ex-Liverpool defender Jamie Carragher believes the club must strengthen their options at left-back.

The Merseyside club demolished Spanish champions Barcelona 4-0 in their pre-season friendly on Saturday evening but Jurgen Klopp fielded make-shift defender James Milner in the first half.

Alberto Moreno remains the only recognised left-back in the squad following their failure to sign Ben Chilwell from Leicester and football pundit Carragher has told Sky Sports that Liverpool must add cover in that position.

“I think the left back area is certainly something that hopefully someone will be coming in after the young lad at Leicester has not come off,” Carragher said on Saturday night.

“But James Milner is playing there and I thought James Milner for 35-45 minutes – I mean the challenge he made in the first half to stop a certain goal – he played very well there.

“But I think you want to be going into the season with one recognised left back. I’ve been critical of Alberto Moreno but hopefully he’ll improve as he’s obviously older a little bit more mature, working with Jurgen Klopp he will improve but it certainly the one area Liverpool need to improve.”

Liverpool were strongly linked with a move for Leicester prospect Chilwell this summer but he snubbed a move to Anfield in order to sign a new contract with the Premier League Champions.

Klopp allowed defender Jon Flanagan to join newly-promoted Premier League side Burnley on a season-long loan on Friday, despite the 23-year-old being capable of playing both full-back positions.

Liverpool have been linked with Lyon starlet Jordy Gaspar and Dutchman Jetro Willems this summer, but neither left-back has made the move to English football.

Klopp has been largely successful in other areas of the transfer market though, capturing Wijnaldum after confirming the signings of Sadio Mane, Marko Grujic, Loris Karius, Ragnar Klavan and Joel Matip.

The Merseyside club commence their league campaign against rivals Arsenal on 14 August and will remain hopeful of adding a new defender before then, but Spanish defender Moreno looks set to begin the season as a nailed on starter.

In other Liverpool team news, Harry Kewell believes that Klopp gives the club a title edge over big-name rivals.
