Carragher was speaking after Liverpool's 2-1 defeat at home to Manchester City on Sunday.
He said on Sky Sports: "Now that was a great game. If you're at home as a neutral, you would have thought what a game that was, but you see the same against Newcastle you see, the same against Bournemouth away, great for the neutral, lost two out of three.
"So the manager's going to have a decision to make again and I'm not just talking about Mo Salah, but I'm talking about a front four.
"I thought, today, the way to go probably would have been putting, I'm not just saying this after the event, I said this before the game, but maybe put them (Florian) Wirtz to the left, maybe playing Curtis Jones.
"I think if Liverpool continue the way they are with a front four - and games end to end- I don't see how they can make the Champions League positions, at all. But no matter what he does, the make-up of this squad, the balance of the team and the squad is not right. It never looks stable, they never look in control.
"Even if the game's exciting, you never feel in control, even when the game is slow and pragmatic, then it never feels like you're fully in control. There's a long road ahead for Liverpool to make the Champions League positions."
