After a slow start to life in the Premier League, Firmino has been showing glimpses of his enormous potential in recent matches and the attacking midfielder produced arguably his best performance in a Liverpool shirt during the 3-3 draw against Arsenal at Anfield on Wednesday night.
Reds defender Toure was one of the many who was left impressed by Firmino's two-goal performance against the Gunners and the Ivorian has gone on to lavish his Brazilian teammate with high praise in the wake of the display.
Toure said: "He's a top player and I'm not surprised what he did against Arsenal.
"He's very technical, and 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."
