The forward got two goals in Wednesday's 3-3 draw.
The Brazilian has been hugely disappointing this season following his big money move from Hoffenheim and has struggled to adapt to life in the Premier League.
He has impressed in the big games though, with impressive performances in the wins over Chelsea and Manchester City earlier in the campaign.
He showed that big game mentality again in Wednesday’s 3-3 draw with Arsenal, bagging two goals in the game, and Toure says he wasn’t surprised as the Firmino does it every day in training.
“He's a good player. He's very technical. He helps the team a lot because he keeps the ball very well,” he told the Liverpool Echo.
“He can run and shoot, he's a top player. I'm not surprised about what he did against Arsenal because he's been doing that in training every day.”
“It's always difficult when you come into the Premier League. You need time for adaptation. But he's done well and he's going to improve, for sure.”
Liverpool will now be hoping that Firmino can put in this type of performance on a more consistent basis.
They have struggled for goals this season, with them having managed just 25 in 21 games so far, a tally less than relegation threatened Sunderland.
Striker Christian Benteke, another expensive summer acquisition, has failed to impress, while Daniel Sturridge has been unable to maintain his fitness for an extended period yet again.
If Firmino could start to get goals for the side on a regular basis, there is every chance he could make the position his own in future.
