It's eight months since Manchester City last lost a Premier League game.
Pep Guardiola's side were in relentless mood as they headed to Watford on Tuesday night, knowing the Hornets had kept just one clean sheet in their last five outings.
Were it not for the efforts of Ben Foster, who made a triple save to keep the visitors at bay, City would no doubt have eased into the lead sooner.
In fact, it took until the 40th minute for the deadlock to be broken.
Riyad Mahrez dipped a superb ball into the box, finding the chest of Leroy Sane as the German netted his fourth goal in five league games.
However, the Algerian's finest moments were still to come as he engineered another City attack on the cusp of half-time, before making it 2-0 shortly after the interval.
It was a class bit of skill. José Holebas tried to close him down and stop him racing towards goal but before he could get near him, Mahrez had swivvled away, turning 360 before he was ultimately hauled down.
Check it out:
You have to sympathise with Holebas - what else can you do in a situation like that?
Robbie Savage described it as a "wonderful, sensational skill...just take a moment to see that. Brilliant."
Gary Lineker tweeted:
"I could watch @Mahrez22 all night. In fact, I will."
The half-time scoreline didn't really reflect City's dominance and Mahrez was just one of a number of players who dazzled.
Across the north-west, Liverpool will have been keeping a close eye on proceedings before they face Burnley on Wednesday night.
The Reds will take little solace in what they saw, however, as City are already looking more and more like champions-elect - and it's still only December.
Guardiola's side have scored an average of over three goals a game this season and in their last two matches, they have kept up that form even without Sergio Aguero.
They've also been behind for a grand total of 12 minutes all season and on that occasion, against Wolves, they came back to earn a 1-1 draw.
There's just no stopping them right now.
