Liverpool made an emphatic title statement with this simply stunning declaration of intent.
Jurgen Klopp's side took the benchmark set by Chelsea a day previously, and raised the bar a notch higher, as they t ore a shell-shocked Watford apart.
Many observers wondered openly whether Stamford Bridge had witnessed the work of champions at the weekend, yet less than 24 hours later, the Reds offered a compelling response that oozed both extravagantclass and ruthless efficiency.
They could so easily have scored 10 here at Anfield, and they did it not against bottom-dragging stragglers, but a Watford side that hadn't conceded a goal in their last three games, in five hours 25 minutes of football in fact.
This was the same team that took Manchester United apart only a few weeks ago, and had risen to seventh in the table, yet the gulf between the two sides was not just measured in league places, but light years.

Ominously, Klopp spoke of his side learning and getting better afterwards, yet in terms of their attacking options, fluidity of movement and sheer bewildering passing symphonies, this was close to perfect.
In fact, perhaps the only thing missing was a dead-eye, clinical vision in front of goal. Before Sadio Mane opened the scoring on 28 minutes, it is no exaggeration to suggest Liverpool could already have been five ahead, with Roberto Firmino, Philippe Coutinho twice, Lucas and James Milner all spurning glorious chances.
Mane showed them how it was done with a fine glancing header from Coutinho's cross, but if the African started the rout, then the victory was firmly made in Brazil.
Philippe Coutinho scores against Watford
Coutinho and Firmino seem to have been having a personal duel in recent weeks, to confirm which of them is the best player in the Premier League right now, and after this artful combination between them, it is still impossible to say.
Coutinho's ability to cut in from the left with his delicate, mesmerising touch and jinking movement is extravagant, as witnessed when he performed the feat to perfection to add a second three minutes later,
But if he was the executor of Watford, then it was Firmino who was architect of their destruction, with his ability to not only create space and create chances, but also to dictate the tempo of the game.
The third came just before the break, with the visitors already thoroughly defeated when their keeper Gomes was carried off after injuring himself trying to keep out Coutinho.
Can tapped in from the inspirational Lallana's brilliant cross, but if that seemed to be the game done and dusted, then Liverpool had different ideas by picking up the breathless pace after the break to score two more immediately.
Henderson and Lallana combined to give Firmino a tap in, then the Brazilian repaid the compliment for Mane. In between, keeper Loris Karius showed some quality with a couple of good saves and some calm distribution as the Reds eased a little.

It allowed Watford a late goal as Daryl Janmaat ran into the box and finished well, but even then the home side were not done, with substitute Daniel Sturridge denied a hat trick when he twice hit the bar and saw two great saves from Pantilimon, before Georginio Wijnaldum completed the rout with his first goal for the Reds.
At the end, they played “Nothing's Going To Stop Us Now” over the tannoy, and if that is a little presumptuous, then you still wouldn't be too keen to put your fortune on betting against it.
