The north London side are currently on the lookout for a new manager after they opted to sack Unai Emery on Friday morning after a poor start to the new season.
Emery left Arsenal with the Gunners having only managed to seal four wins from their opening 12 games in the Premier League so far this season.
The Gunners have been widely criticised for their below-par performances this season and they have struggled to find consistent form in all competitions this term.
Arsenal signed David Luiz from Chelsea FC in the summer but he has failed to bring some much-needed stability to the back four at The Emirates.
And former Liverpool FC defender Carragher feels that it is Arsenal’s back-line that has been letting them down in recent weeks.
Speaking to Sky Sports News, Carragher said: “The feeling was this man was going to come in and change things, but it’s actually worse, and less organised than it was towards the end of Arsene Wenger’s reign.
“There’s no doubt that Arsenal, with the squad they have, are underachieving.
“I do think they’ve got really poor defenders, I’ve got no time for some of the players they have at the back, they are really poor.
“The next man they bring in, of course it will be a big job, they’re a long way from Liverpool and Man City, but it will be interesting to see if they go back to Mikel Arteta, or look at the job Brendan Rodgers is doing, or a top-level Champions League manager in Max Allegri. Or do they wait for someone in the summer?”
Arsenal – who have brought in Freddie Ljungberg as their new manager – are currently gearing up for their trip to Norwich City in the Premier League on Sunday afternoon.
They will then turn their attentions towards their home clash against Brighton and Hove Albion next week.
