Manchester City have been here before, of course.
Their rampaging start to last season conned most observers into thinking they would have the Premier League title by Christmas.
But they could not sustain their remarkable run and Chelsea ultimately left them for dust in the title race.
This season, however, it would appear Pep Guardiola has got it all worked out and is going to rewrite the Premier League record books along the way.
Unbeaten after eight matches, with seven wins, Guardiola's Galacticos had scored 29 goals and conceded only four.
The five clean sheets would indicate the club's huge summer investment in a new goalkeeper and defenders is paying dividends too.
At this rate, City could rival Arsenal's Invincible team of 2003-04 and conceivably go the season unbeaten.
It would seem an impossible task, but try telling that to Arsene Wenger and his players.
Remaining unbeaten is perhaps far-fetched at this stage, although the first game they might not be expected to win is not until they go to Manchester United on 10 December, but other records could tumble.
Bar the blip of a 1-1 home draw with bogey team Everton, who also drew with and beat them last season, City have scored freely.
They are the first top-flight team to score 29 in their first eight league games since Everton hit 30 in 1894-95.
The seven-goal demolition of Stoke was the most impressive to date, but the signs were there as they also scored five against Liverpool and Crystal Palace and six of the best against Marco Silva's impressive Watford side.
If they keep this up, they will score over 135 goals before winning the title.
To put that in perspective, the record is 103, set by Chelsea in the 2009-10 season.
That was when Didier Drogba terrorised English clubs with 29 league goals and Carlo Ancelotti's side were imperious as they swept to the Double.
City were one goal shy of breaking the Londoners' record just four seasons later.
Liverpool also broke the magic 100-goal barrier that season as they finished runners-up with 102 goals.
And to show just how hard it has been to score so freely, no other side has made it up to three figures.
Manchester United got to 97 goals in 1997 and 2000 and City's next best effort in the list is the 93 goals they scored in 2011/12.
Perhaps proving they have the all-round package in place, Guardiola's side have the best goal difference of any team in the top five European leagues in all competitions this season (+33).
They have, of course, looked good and scored goals in the Champions League and Carabao Cup too.
Reflecting on what his team is doing after the Stoke match, Guardiola made it clear that he is here to win and not entertain, however.
He mused: “Team perfection? I do not know as you can always do better, but against Stoke was the best performance since I arrived.
“We played quick, simple, and I am very pleased because we win and the way we won.
“We speak in training about starting well and being aggressive and when we concede a foul – play on. When it is a throw-in – play on and do our game.”
Like his brilliant Barcelona side, there is no let-up with City – with or without the ball.
And do not get him started on one-man teams!
He explained: “You can not score seven goals unless the whole team is not playing well and I am very pleased. The fans enjoy it and I am a spectator as well as a manager and I enjoy my job.
“I am here to win and not here to entertain. Last season when people said we had to change way we play I said that is not going to happen, but we will improve in order to win.
“Now confidence is so high and everyone believes no matter who plays we will play well and score many goals, but we are creating a lot more too. We want to play in front and be attacking here in the Premier League.”
The Perfect Goal
It is very much Total Football, just as Guardiola was raised under the tutelage of the original Dutch Master Johan Cruyff.
The late Ajax and Barcelona legend was schooled in the art of Total Football by coach Rinus Michels, when Holland were the team to watch in the Seventies.
See how Guardiola is happy to play good footballers in any position. Who thought Fabian Delph would make a top left-back before?
In the 2-1 League Cup win over over West Brom they scored what probably should be the goal of the season – however spectacular a Scorpion Kick is to watch.
City completed a 52-pass move with every member of the team, including the keeper, touching the ball at least twice before Leroy Sane finished.
Since Opta began keeping those records, the most passes leading to a goal in the Premier League is 48, in the build-up to Nacer Chadli’s strike against QPR for Tottenham in 2014.
That, to the Catalan coach, is how football is played at the very top level.
