The Reds were held to a 0-0 draw by Everton on Sunday, leaving Manchester City one point clear at the top of the Premier League table.
Liverpool created chances at Goodison Park, most notably for Mohamed Salah and Fabinho, but could not breach Jordan Pickford’s goal.
You can read 16 Conclusions on a game which Carragher believes highlighted one of their main issues.
The Sky Sports pundit feels the inability to replace Philippe Coutinho with Fekir last summer could prove fatal to their title chances.
Fekir almost moved to Anfield but the move collapsed after he was asked to undergo two medicals due to a knee issue.
Carragher was asked during the game on Sunday whether Liverpool have a problem, and replied: “Yes, in terms of the make-up of the midfield.
“But it’s not just a problem now, I think that was even a problem if you go back to the end of last season.
“They lost Coutinho last January and they never replaced him. They tried to replace him with someone from Lyon in the summer but they couldn’t get him, there wasn’t three or four different options.
“So it’s not just a case of right now, in the summer, even if Liverpool win the league, it is still a position I think they will try and fill because it’s not just a case of one player going in there and being the best player. They don’t even really have that type of player off the bench.
“But when you’re talking about that being a problem, I don’t think there should be massive panic for Liverpool after today or this week’s games because they don’t look like conceding a goal – that’s back. It was there in the first half of the season and that is now five clean sheets on the bounce.”
