Carragher insists Salah's current form doesn't warrant a starting place in Slot's XI.
"If you're not scoring the goals at one end and you're leaving your team your exposed at the other you're basically getting nothing from this tactical ploy of allowing Mo Salah just to stay up top," Carragher said on The Overlap.
"So he's either got to come back or you've got to play someone else.
"That's why I said a few weeks ago the days of Mo Salah starting every week especially away from home, have to stop."
Former Reds defender Steve Nicol agrees with Carragher and said on ESPN: "You have to try and figure a way out to get him back to somewhere near his best. And so far, playing him and playing him and playing him isn't working.
"I got excited when he scored a couple of goals in a couple of games (against Brentford and Aston Villa), but his overall performance hasn't really changed much other than those two goals. Now the only other thing you can do is sit him on the bench. Sit down, have a look, maybe a different perspective.
"Then play him the next game and let's see if there's any sort of reaction because unfortunately he's reached the stage now where the team can't carry him anymore. Simple as that."
