Jamie Carragher believes Liverpool's ownership group must take their share of the blame for the team's current blip.
Carragher feels the Reds are paying the price for not yet signing a centre-back to cover for long-term injury victims Virgil van Dijk and Joe Gomez.
Jurgen Klopp's men have now gone five Premier League matches without a win - and saw their club record unbeaten home run ended by a 1-0 defeat to Burnley on Thursday night.
That has left Liverpool fourth in the table - six points behind leaders Manchester United - in their bid to retain the title.
"Since 2015, Liverpool’s owners have allowed Klopp to be the symbol of the Anfield revival, the figurehead as well as the coach and inspiration behind the Champions League and Premier League triumphs," said Carragher in his Telegraph column.
"The relationship between a low-key, overseas ownership group and charismatic front of house leader has worked. Fenway Sports Group have been the first to acknowledge the club would not have restored its elite status without Klopp, and he has been generous in his praise for how they support him, and granted him the freedom to manage without boardroom intrusion.
"But when I heard Klopp assume all the responsibility for Liverpool’s latest defeat to Burnley on Thursday night it did not sit comfortably with me, especially when he pointed out that it is not for him to decide if the club acts in the transfer market. In the midst of the first significant backwards steps since Klopp’s appointment, there must be a collective effort to ensure this is a just blip.
"I believe the club’s response should have been activated on October 19, the day Virgil Van Dijk’s cruciate knee operation was confirmed. Hindsight is unnecessary. I said then I did not think Liverpool could win the league unless they had a new centre-back in place on January 1. They needed one before Joe Gomez was injured. His and Joel Matip’s appearance record was informative of that.
"Frankly, it is preposterous that three months on and with the transfer window now open, Klopp felt compelled to use Jordan Henderson in the position against Manchester United. And although Fabinho has been outstanding, he would be more influential in midfield. It has caused a chain reaction throughout the team.
"Maybe the club thought Klopp is so good he can overcome any situation. If so, the last few weeks are a reality check for them."

Carragher later added: "I believe this time the club needed to react in the transfer market to ensure these most trying of times do not undermine Liverpool’s upward trajectory.
"I said in the summer successful teams need refreshing from a position of strength, and the club bought Thiago and Jota.
"Now, because of injuries, a response was needed to address a visible and serious area of weakness.
"That requires players good enough to start the biggest games, not to step in and do a job occasionally. To be more specific, it demanded a new centre-back."
