Once upon a time, Liverpool were attempting to create "death by football."
One of Brendan Rodgers' most colourful soundbites, the then Liverpool manager was outlining a grand vision for his new team to pass the opposition into submission.
It was 2012 and it was Spain's model of possession-based football that ruled the European lands. La Roja had won back-to-back European Championships either side of the 2010 World Cup with a hypnotic passing game designed to squeeze the life out of opponents.
Spain's success - and Barcelona's at club level - saw the style become fashionable across the continent as diminutive playmakers were shoe-horned into teams in an attempt to copy and replicate the passing carousel provided by the flawless talents of Andres Iniesta, Xavi and co.
"When you’ve got the ball 65-70 per cent of the time it's a football death for the other team," said Rodgers in September 2012.
"We’re not at that stage yet, but that’s what we’ll get to. It’s death by football."
Such a methodology - despite its Spanish-fused success - has never tallied with Jurgen Klopp's masterplan. Certainly not at Liverpool.
In contrast, the Reds manager has always championed the full pelt. It's hell for leather, high octane, thrash-metal football.
It's become a cliche during Klopp near four-year stint as Liverpool manager, but his way of playing has broadly been boxed in that way given some his team's electric performances throughout his time on Merseyside.
Manchester City, Roma, Arsenal and Barcelona - to name just four - have all fallen victim to a turbo-charged Liverpool burst at various points of Klopp's reign.
The irrepressible, pressing machine is the default way under the German at Anfield, even if more pragmatic tweaks have occasionally been tailored to suit circumstance.
Klopp's tactical dogma differed from the en-vogue philosophies that dominated football at the turn of the decade.
"It is not my sport," he once said. "I don’t like winning with 80% possession. Sorry that is not enough for me. Fighting football, not serenity football, that is what I like."
The Reds boss developed and honed his way of playing under mentor Wolfgang Frank, whose penchant for pressing was said to have been adopted from legendary Italian coach Arrigo Sacchi.
As Klopp moved into the latest phase of his Liverpool team's development at the beginning of the season, the Reds chief spoke of the intensity he wanted to instil into his charges.
"We want to be intense - more intense than other teams," he said. "There's not a competition for it, but it's a title you can win, to be the most intense team.
"That's what we want to be, however you want to measure that. If we are that and mixed with our quality and the potential that we have, it could be good football and successful football. That's the plan."
"The plan", it seems, is in perfect working order.
"I’ve never seen anything like what I saw at Anfield," admitted Arsenal midfielder Dani Ceballos, this week.
The Gunners star was hooked after an hour on August 24 after being dizzied and dazed by a Liverpool midfield who swarmed their visitors from the first minute.
A player steeped in the tiki-taka traditions of his Spanish homeland, the ball-playing Ceballos, who is on loan from Real Madrid, was left breathless by the suffocating red blurs he encountered in last month's 3-1 defeat.
"I haven’t seen a team that plays better, that presses like them, the way the fans carry them along," he conceded.
"They take the air from you. You spend so much time defending and when you want to do something with the ball, when you want to breathe, they’re back on top of you. They’re very well-drilled."
Such claims will be exactly what Klopp has set out to hear from opposition footballers at Anfield since he moved to Merseyside in October 2015.
This, he might feel, is his tactical panorama in full view for all.
So far, it's been enough to move the European champions two points clear at the summit of English football as the Reds hunt down a first league title in 30 years.
Death by football? Not anymore. Klopp's style is aiming to make his Liverpool team immortals.
