Jamie Carragher has outlined his fears for Roberto Firmino amid Liverpool's worrying goal drought.
The Reds' 0-0 draw against Manchester United on Sunday meant Jurgen Klopp's side have failed to score in their last three Premier League games.
Liverpool have failed to win any of their four games since a 7-0 thrashing of Aston Villa last month, and have scored just one in that time, with Sadio Mane netting in a 1-1 draw against West Brom.
Carragher says the Reds' fabled front three of Firmino, Mane and Mohamed Salah will “broken up” over the coming years.
And he fears Firmino, who has netted just five times this season, could phased out of the Liverpool attack if he doesn't up his goal contribution.
"When we talk about this Liverpool team, we talk about the front three," Carragher said on Sky Sports’ Monday Night Football.
"It's almost like they come as a package. The reason I say that Liverpool's front three is unique is not that they are better than other front threes, it's how long they've stayed together.
“They are all getting to their late 20s and sooner or later that front three will have to be broken up .
“You can’t, in two years’ time, say ‘we’re going to buy a new front three’ and replace them all. It will change over time."
Liverpool signed Diogo Jota from Wolves in the summer, and he hit the ground running, scoring nine goals before being sidelined by injury.
Carragher fears Firmino could be the first of Liverpool's forwards to be ousted if he doesn't add more goals to his game, with the Brazilian having missed chances against United.
He said: “I am still confident Mane and Salah will start scoring goals again. I must say I am worried for Firmino.
“He has never been seen as ‘the’ goalscorer. That is the responsibility of the other two, but he is there to chip in.
"When they are not scoring, he has to be a bigger goal threat.
"Yesterday (during the 0-0 draw with Manchester United) he had a couple of chances but did not quite strike the ball right."
