That’s the view of pundit Tony Cascarino who has seen Firmino struggle at times this season.
The Brazilian shone for Liverpool last campaign, alongside Sadio Mane and Mohamed Salah.
Firmino netted 15 Premier League goals last season but has just two to date this term.
Liverpool are unbeaten domestically though have tasted defeat in Europe, with Napoli beating the Reds.
Jurgen Klopp’s side return to Champions League action by travelling to Red Star Belgrade tomorrow (5.55pm).
And Cascarino would not be shocked to see Firmino left out for the clash in Serbia.
“Roberto Firmino looks to me like he needs a rest and I wouldn’t be surprised to see Jürgen Klopp leave him out of one of the next few games,” Cascarino wrote in his column for The Times.
“He’s a wonderful player but in the past nine of his appearances for Liverpool he has scored once — against Red Star Belgrade — and not managed a single assist.
“He’s played in 69 games since the start of last season, more than any other player in the Premier League. Even Mo Salah has played two fewer.
“He would benefit from a break to freshen him up.
“Some players react less well to more competition for their place and I wonder whether Firmino is one of those.
“Daniel Sturridge, Xherdan Shaqiri and Adam Lallana are all challenging him for places in the team at the moment and that may have made Firmino less comfortable.”
Despite being unbeaten in the league, Liverpool have failed to match the scintillating form from last season.
But it’s the Reds’ defending that has irritated Klopp the most.
Following a 1-1 draw with Arsenal at the weekend, the German said: “I am not happy with how we defended in the first half, that is not what I want.
“We were outstanding on the counter attack.
“It’s a point, we take that, and a point at Arsenal is always a good result but we could have won.
“We had clear chances, they had chances as well.”
