Liverpool are not battling through "a blip" but a "serious problem", according to club great Jamie Carragher.
Jurgen Klopp's side sit ninth in the Premier League, 13 points off the top ahead of Arsenal's meeting with Nottingham Forest on Sunday, after falling to defeat against Leeds United on Saturday.
Crysencio Summerville's late strike snatched an unlikely victory for strugglers Leeds as Liverpool suffered their first Premier League defeat at Anfield since March 2021, ending a 29-match home unbeaten run in the competition.
Despite Mohamed Salah cancelling out Rodrigo Moreno's early opener, Illan Meslier made a series of impressive stops to help pave the way for Summerville's winner, and Carragher feels his former side face a worrying situation.
"It's a huge result for Leeds but Liverpool have got massive problems," Carragher said in his role as a pundit on Sky Sports.
"Leeds' fans know how big a result this is. It's so long since anyone's won at Anfield. They're going to milk it and rightly so. It will do wonders for them, in terms of the league table.
"This isn't a blip for Liverpool, this is a serious problem. There's no doubt that the goalkeeper in the last 10-15 minutes has kept Leeds in it but if you look at the whole game you can't say Leeds haven't deserved to get something from it. They were fantastic.
"Klopp must be thinking, what else can I try now? Different permutations, formations, personnel."
Klopp again bemoaned a lack of consistency, lamenting the injury issues Liverpool face, though Graeme Souness offered a scathing assessment of his former side's capabilities.
"Liverpool are a country mile from where they were over the last few years," Souness added. "In many instances, Leeds were more than a match for Liverpool and they did to Liverpool what they had been doing to teams for years.
"Liverpool basically bullied teams before, their midfield bullied teams. And now they're being bullied. That's making them vulnerable at the back, and they're not creating the same chances up front. Liverpool are a shadow [of the team they used to be].
"Liverpool still had enough chances to win the game, but they are not like the Liverpool we've seen for the last five years. They don't play with the same intensity and just don't have it in their legs anymore."
Souness pinpointed Liverpool's midfield as a primary reason for their struggles.
"If correct [Leeds ran 11 kilometres more than Liverpool], then to a man they ran a kilometre more than Liverpool. That's a big difference," he continued.
"And if you look at a midfield of Thiago [Alcantara], 31, [Jordan] Henderson, 31, Fabinho, 29, then after that you have [Naby] Keita and [Alex] Oxlade-Chamberlain, Curtis Jones who is 21, and Harvey Elliot who's 19.
"If you go back to the start of the season, Jurgen [Klopp] must have looked at his midfield and thought: 'We're vulnerable here'. I feel their midfield is no longer a midfield that is going to get them back and win the big trophies."
