Packed out in the away end of Leicester's King Power Stadium on Monday night, with their team cruising through a first-half brace from Curtis Jones, Liverpool supporters took a collective in-take of breath and began their loop.
There was something that the travelling Kop wanted Roberto Firmino to know. "Si senor," they began. "Pass the ball to Bobby and he will score. Our number nine, give him the ball and he'll score every time."
The ode to Firmino, one of the catchiest terrace anthems in modern memory, was sung loud and long into the Leicester night as those who had made the journey for the penultimate away game of a difficult campaign on the road made their admiration known.
