Jurgen Klopp stressed the need for Liverpool's attackers to step up in the absence of Mohammed Salah and Sadio Mane, ahead of their Premier League clash with Brentford at Anfield.
With Salah and Mane featuring at the Africa Cup of Nations, Klopp's side struggled to create clear-cut opportunities last time out, in a goalless draw with Arsenal in the first leg of their EFL Cup semi-final.
Following a six-game winning run in November and December, Liverpool are also winless in their last three Premier League games, throwing away a lead to draw two of those games.
Speaking ahead of Brentford's first trip to Anfield since March 1989, Klopp praised the contribution of Roberto Firmino, before calling for other players in his Reds squad to step up.
"He [Firmino] is a very smart player", Klopp said in a news conference. "His game is about using his team-mates in the way that he can use them.
"It's not just about being able to score goals in this way or that way.
"In one of our biggest games in recent history we played without Mo [a 7-0 win at Crystal Palace in December 2020, where Salah spent the first hour on the bench], and we won against Manchester United [a 5-0 victory earlier this season] without Mane.
"Now both are out, and that is not cool, but we don't think [of Firmino] 'you have to be like him or like him'".
Salah and Mane have scored 24 Premier League goals between them this season, on par with their combined expected goals (xG).
Firmino, meanwhile, has only netted four league goals this campaign, with an October hat-trick against Watford representing his only Premier League strikes since the opening day.
Klopp was also asked about the role of versatile youngster Curtis Jones, who made a lively cameo from the bench in Liverpool's frustrating draw with the Gunners, and stressed the need for Jones to show greater consistency.
"I had a long talk last week with Curtis," Klopp said. "I love the boy, I love the potential he has, but we have to make sure he makes those next steps, and fulfils that potential on the pitch.
"You have these kinds of conversations when you are not 100 per cent happy with a player in that moment. We have to find a way for him to show this [potential] much more often."
Jones provided just one goal and two assists in 24 league appearances last season, featuring regularly as Liverpool battled an injury crisis, and Klopp highlighted the need for the midfielder to contribute in the absence of the side's bigger names.
"It's an ongoing process between Curtis and me. We've had a tricky period, especially with Covid, which is not helpful, but now we'll try to make sure he can show how good he can be," Klopp added.
