Jamie Carragher believes the title is "slipping away" from Liverpool and thinks his former club will be concerned about missing out on the top four after losing to Burnley.
The Premier League champions were beaten 1-0 at Anfield on Thursday night, bringing an end to their 68-game unbeaten run at home.
It means that Liverpool are now winless in five Premier League matches and haven't scored a league goal in 2021.
To make matters worse, Liverpool are now four points behind Manchester City and six adrift of league leaders Manchester United, having played a game more than Pep Guardiola's side.
With Tottenham and Everton able to jump above Liverpool, in fourth, if they win their games in hand, Carragher believes chances of retaining the title are waining and the club may even be concerned about qualifying for the UEFA Champions League.
“We’re talking about a blip for Liverpool and Jurgen Klopp has come out and defended his players as you’d expect, and these players have done so much for Liverpool," Carragher told Sky Sports after the full-time whistle.
"But at this moment, they look like the title is slipping away. You think it’s gonna be really difficult. At this moment, yes, it looks like six points from the top, that can still be recovered, the fixtures they have in the next couple of months.
"I think Liverpool in the next couple of weeks will start worrying about the top four positions rather than the title. They need to get back to winning games, scoring goals.
Manchester United beat Fulham 2-1 thanks to goals from Edinson Cavani and Paul Pogba.
Pogba once again turned in a high-class performance as Ole Gunnar Solskjaer's side reclaimed top spot in the Premier League. Now United turn their attention to another clash with rivals Liverpool, this time in the FA Cup fourth round.

"He’s got a lot to ponder, you can’t quite believe what’s happened to Liverpool in the last few weeks. You go from that 7-0 win over Palace, so many players out of form at the same time.
"There are so many teams this season that are challenging for the top four, that will be a concern for Liverpool until they get out of this poor form.”

He added: "For whatever reason, this season, it’s not just dropped off - it’s massively dropped off in the last five games, really.
"It’s a huge worry going forward, not just in terms of the title, but for the top four positions.
"There are so many teams that will fancy their chances this season in terms of that goal and at this moment Liverpool are massively out of form and have a really difficult run of fixtures.
"If they don’t go well, they’ll be completely out of the title race by then, by the middle of February, the end of February. If that happens, Liverpool will be fighting for their lives to get in the Champions League next season.”
