The Gunners' terrible away record at their fellow Top Six rivals continued on Sunday thanks to Sergio Aguero's hat-trick in Manchester City's 3-1 win.
And former Liverpool star Carragher, 41, knows where the blame should be placed.
He said: "Not just today, Stephan Lichtsteiner is not good enough.
“Maybe you could argue that’s because of his age and the fella next to him Shkodran Mustafi has never been good enough since the day he walked through the door and that’s why all the goals came down there.
“To see Arsenal defend like that really, there’s a big job here for Unai Emery to do.”
It is fair to say Carragher – who had to apologise for mispronouncing Lichtsteiner's name on Sky Sports – knows a thing or two about defending.
He is, after all, considered one of the best defenders of the Premier League era. In his career at Liverpool, he racked up 508 appearances, keeping 195 clean sheets and conceding 173 goals, just ONE of which came from his error.
As he rightly said, all three of the goals came from the Arsenal right with Stephan Lichtsteiner singled out as the main culprit.
At 35, he has not got up to speed with the Premier League since arriving from Serie A last summer.

His struggles have highlighted the importance of Hector Bellerin, the first-choice right-back, who is out for the remainder of the season with a cruciate knee injury.
Former Arsenal defender and fellow Sky Sports pundit Alex Scott was also damning in her assessment of her beloved club.
She said: “Lichtsteiner, I have to say, wasn’t good enough today.
“You can see with [Alex] Iwobi, starting to help double up down that area because you can see that was the weak link today.
"Every single goal, it was a repeat pattern, it didn’t change but ultimately City were at another level.”
