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.

The man himself, who, despite his outward flamboyance, has always looked vaguely uneasy as the centre of attention, could only flash that trademark smile in the general direction of the thousands who continued to belt out his name.
Firmino has been sidelined for the last six matches with a muscle issue but still opted to be part of the travelling squad alongside the injured Darwin Nunez - and the outgoing No.9 was no doubt impressed by what his colleagues on the pitch served up in his absence as they made it seven successive Premier League victories and extended their unbeaten run to nine matches.
The former Hoffenheim man, however, will have been more in awe at those cheering him at King Power as Firmino's unique ditty - set to the tune of Y dale alegria a mi corazon, by Argentinian musician Fito Paez - was belted out for close to 10 straight, unrelenting minutes.
It was a remarkable show of appreciation that was only silenced when Trent Alexander-Arnold arched home a stunning strike to make it 3-0 with 71 minutes on the clock.
But that wasn't to be the end of the Reds supporters' serenading of Firmino, who went over with the rest of his team-mates at full time to thank them for their efforts. The Brazilian's beaming, megawatt smile as he left the stadium with Arthur Melo and Nunez to board the team bus said it all about his night on the sidelines. It will surely be one of countless treasured memories for the forward as he enters the final few weeks of a decorated eight-year spell on Merseyside.
There won't be a dry eye in the house on Saturday afternoon at Anfield as Firmino gets set to call time on a hugely successful spell at Liverpool. The club remain hopeful that he will be cleared to be part of the match-day squad as he aims to get back to fitness but whether or not he features against Aston Villa, there will be ample recognition of his achievements from fans, players and the club as a whole this weekend. He, perhaps more than any other, personifies the Jurgen Klopp era.
But while those at the King Power on Monday night were doing nothing more than making a firm point about their beloved No.9, perhaps they were also inadvertently sending a message to those who are not yet at Liverpool?
As the Reds continue to assess the market with regards to their summer transfer targets, Liverpool are retaining an interest in several with Brighton's Alexis Mac Allister at the top of the wanted list this coming transfer window.
Liverpool, it is understood, are braced for competition for the Brighton midfielder in the shape of Manchester United, who are also said to be tracking the Argentina World Cup winner.
Brighton boss Roberto de Zerbi was surprisingly candid in his acceptance that he could lose both Mac Allister and Moises Caicedo this summer in the wake of his team's 3-0 win at Arsenal on Sunday and the former's decision could yet be based around who qualifies for the Champions League at the end of this season.
Liverpool's top-four plans, despite a stirring end to the campaign, remain alive in more hope than expectation at present but the away end of Leicester's stadium on Monday night should be viewed as a clear memo for anyone of interest for the Reds this coming window: Be successful at Anfield and you will be adored like perhaps nowhere else. That must be quite the incentive.
On the face of it, the ceaseless chanting in Firmino's direction was a message only of respect to a departing great of the modern day. Unintentionally, though, it was also one sent to anyone who might be thinking about following that same path.
