Much was made of the loss of Coutinho to Barcelona but the numbers being generated by his compatriot may mean the Reds move on quicker from that £142million sale than anyone anticipated.
Firmino has long been a favourite of manager Jurgen Klopp because of his hard running and ability to press at the head of the attack and despite initial criticism he was not a centre-forward, the 26-year-old is also delivering where it matters.
"I don't think that it's possible that somebody could get more credit, compliments, praise, whatever you want to say as Roberto gets from us," Klopp said.
"But it's well deserved - everything. He's a fantastic football player.
"You see him in training and think 'what a work ethic, what an attitude', and he brings it on the pitch as well.
"He never rests. You have to pull him out, you have to tell him 'come on, stop, sit here, calm'.
"I hear in the stadium (Anfield) that people like him - good idea - but I have no real idea if anybody thinks he's not important or whatever. I'm not too interested, to be honest.
"I'm pretty sure if I give the players the opportunity to have a free choice in training (to) build teams by themselves Bobby is one of the first they would pick.
"(It's) nice to have him around - better to have him than in the other team. That's maybe the best thing you can say about a football player."
