Thomas Tuchel has turned Chelsea into an unstoppable force of nature.
Given the troubles that blighted Frank Lampard's second season at Stamford Bridge, you'd be forgiven for thinking that Tuchel would need several months to get the Blues back on track.
However, clearly Roman Abramovich's heavy spending last summer just needed Tuchel's arrival to unlock its quality because Chelsea are on the verge of an astonishing 2020/21 campaign.
Tuchel's lightning start
The west London club overcame Atletico Madrid, FC Porto and Real Madrid to book themselves a place in the Champions League final and domestic football has been equally as kind.
Besides, Chelsea will have the chance for more silverware in the FA Cup final against Leicester City and they're entering the final weeks of the Premier League season as heavy top four favourites.
And that couldn't have been any clearer than when Chelsea secured an impressive 2-1 win at the home of soon-to-be champions Manchester City on Saturday night.

Goals from Hakim Ziyech and Marcos Alonso overhauled Raheem Sterling's opening strike as Tuchel once again outwitted Pep Guardiola in a tactical chess match.
As a result, Tuchel can now put his feet up and enjoy one of the finest Premier League records ever established by a new manager, remarkably losing just one of his 16 matches in the competition.
It's a fantastic record that places Tuchel amongst the very best coaches that the Premier League has ever seen and only Guardiola can lay claim to a better points-per-game ratio in the division.
Best points-per-game in the Premier League
Uh huh, you really did read that right because on the back of Tuchel's latest masterclass, we turned to Transfermarkt to see how his statistics rank within the Premier League's 29-year history.
And of all the managers to have coached at least five games in the top division since its 1992 rebranding, Tuchel's average of 2.19 points per game impressively ranks him in second place.
That's pretty good going, I'm sure you'll agree, so be sure to check out who's breathing down Tuchel's neck as some of the all-time Premier League bosses most familiar with that winning feeling:
You know you're doing something right when you're above Sir Alex Ferguson, that's for sure.
Tuchel rubbing shoulders with icons
Now, the obvious caveat here is that it's still monumentally early days for Tuchel and to say that Chelsea managers have a short lifespan would the mother of all understatements.
So, don't think for a second that Tuchel will necessarily be relaxing on the podium for seasons and seasons to come, but it really goes to show how brilliantly he's hit the ground running in England.
However, it's certainly telling that it still sees him finish comfortably short of Guardiola who will likely be considered second only to Ferguson when he wins his third Premier League title in four years.
And with the best points-per-game ratio of any head coach despite having managed in the competition for over four seasons, it's fair to say that Guardiola would deserve such lofty praise.
Nevertheless, as yesterday's action at the Etihad Stadium goes to show, being one of the greatest managers of all time is futile when it comes to a one-off battle with Tuchel.
