The Brazil international has struggled to hit consistent top form in the Premier League this season following an exhaustive World Cup campaign.
Firmino, though, scored a hat-trick in Liverpool FC’s 5-1 win against top-six rivals Arsenal at Anfield last month before his header in a 2-1 loss at Manchester City on Thursday night.
The South American has scored eight goals and has made three assists in 22 appearances in the Premier League this season.
Firmino brings more than just goals and assists to Klopp’s team, with his unselfish running off the ball regularly providing space for his team-mates.
And Klopp, who is looking to become the first Liverpool FC manager to win the Premier League, lavished praise on Firmino for his input.
“It [the hat-trick against Arsenal] is nice and very important for him,” Klopp is quoted as saying by Metro.
“It was nice and so deserved for him. He’s a very, very important player for us.
“As an offensive player, he needs obvious credit and that is goals. There was talk about him and is he clicking.
“He played all the time really. He wouldn’t do that if he wasn’t influential. He works so hard for us and is influential in everything.”
Firmino moved to Liverpool FC in a £29m deal from Bundesliga side Hoffenheim under Klopp’s predecessor Brendan Rodgers.
The South American forward is still waiting to win his first piece of silverware at the Merseyside outfit.
Firmino has played in Liverpool FC’s losses to Manchester City, Sevilla and Real Madrid in the League Cup, Europa League and Champions League finals.
