Firmino joined in the summer in a £29 million deal, and has shown flashes of what he can do.
Firmino signed from Hoffenheim for £29 million in the summer and has lately been used by manager Jurgen Klopp as the central striker, while his preferred role may be in the number 10 position.
It took the 24-year-old a little while for him to show what he could do for the Reds before a 4-1 win over Manchester City in November saw the Brazilian at his best along with fellow countryman Philippe Coutinho as well as Adam Lallana.
Now he has five goals to his name after recently picking up the club's Player of the Month award for January.
He told the official Liverpool website: “When I arrived here I expected it to be much easier to settle, but the first and second month were somewhat difficult.
“But I can say that I am getting used to everything now and things are improving. And I am feeling more comfortable in the environment.”
He has shown flashes of what he can do and Liverpool fans will want to see performances he has shown against Arsenal, Manchester City and Norwich on a more consistent basis this season. His eye for a good pass has also not gone unnoticed.
Maybe it's a sign that we'll see more from Firmino next season. After all, he has been playing in a side that has had its season blighted by injuries to forwards - with Danny Ings, Daniel Sturridge and Divock Origi all sidelined recently - and Firmino has led the line as Klopp has seemed unconvinced that Christian Benteke is up to doing the job.
That, and his time adapting to life in England, has probably prevented many Liverpool fans from seeing him at his best, and when Philippe Coutinho returns from injury - who Firmino said they'll welcome back with open arms - it will give that bit more freedom to Firmino.
