The former England international thinks that Firmino was absolutely stunning in the Reds' 4-2 win over Hoffenheim on Wednesday night.
"Every time Liverpool won possession, the switch of play, because the line was so high with the back three, they caused them all sorts of problems," Gerrard said on BT Sport.
"Roberto Firmino's performance has been absolutely stunning.
"His quality, his vision, he keeps getting Liverpool players in.
"It was stunning, one, two touch football.
"Every time Roberto Firmino gets the ball, if you're a runner in this team, your eyes light up and you get on your bike.
"He drops in deep, lays the ball off and this little dink with your left foot to put it on a plate for Emre Can is world class."
