The moral of this week's Champions League story is don't ever write off a Jose Mourinho side because even in the twilight of his managerial career, he can mastermind the improbable on any one-off day.
As Benfica secured a play-off spot in the most dramatic way imaginable last night, the 'Special One' reminded us that not all his magic has been lost.
Under the European lights, Mourinho still shines bright.
Star player - Joao Pedro
Joao Pedro has made an electric start to life under the new Chelsea manager, Liam Rosenior. After a brace last night to inspire Chelsea to a comeback win in Naples, the Brazilian striker has now scored four goals in four starts under the Englishman.
Pedro had been relatively quiet leading up to his equalising goal just past the hour mark, but it was some way to introduce himself to the occasion. After picking the ball up on the edge of the area, Pedro unleashed a cannon that flew into the top corner with unstoppable speed and accuracy.
Pedro then completed the comeback after a smart one-two with Cole Palmer before ignoring the run of Alejandro Garnacho inside the box and finding the bottom corner with a low-driven strike.
It was two world-class moments of quality from a player enjoying himself under his new coach, something that will come as a relief to Chelsea fans who have been frustrated by his inconsistent performances.
Surprise package - Bodo/Glimt
Bodo/Glimt are the side that just keeps on giving in this season's Champions League. After their impressive shock win against Manchester City last week, they were surely not to be underestimated by Diego Simeone and Atletico Madrid this time out.
And they didn't. Simeone selected a strong side, and on paper, it had more than enough firepower to secure the three points.
Julian Alvarez and Alexander Sorloth led the visitors' attack, and the latter would fire Atletico into an early lead. However, Bodo/Glimt refuse to go down without a fight.
The away side equalised through talented midfielder Fredrik Sjovold before half-time, but they needed another to qualify for the play-offs.
It was always a big ask against a European giant like Atletico, but Bodo/Glimt seem to thrive in moments of improbability.
They love proving those who underestimate them wrong.
So when the hero from last week, Kasper Hogh, netted in the 59th-minute in what would prove to be the winning goal that sent his side into the play-offs, they did exactly that.
How far this fairytale story will go remains to be seen, but the fact that it is still alive after eight matches against Europe's biggest clubs in their UCL debut is already a story that will be immortalised in Bodo/Glimt's history.
Team of the week - Benfica
Benfica's play-off qualification hopes were on the ropes heading into a fascinating clash against Real Madrid last night. With just six points from the first seven matchdays, Benfica needed to win and hope results went their way to qualify. As it turned out, they needed even more than that.
Despite dominating the match and outclassing Alvaro Arebola's Madrid, the Portuguese giants' sensational 3-1 lead became 3-2 when the ruthless Kylian Mbappe completed a brace just before the hour mark.
Despite Real not being at their best, it was a brilliant performance from Mourinho's men to be ahead and seemingly back in control of their own destiny.
Despite having just 33% possession, Benfica's xG of 3.0 was superior to Real's of 1.50 and eight big chances created to Real's three is proof of their dominance in the area of the field that matters the most.
It isn't an exaggeration to call it a Mourinho masterclass.
Benfica thought their 3-2 lead was enough to sneak into the top 24, but late drama elsewhere meant they needed a fourth goal.
In a chaotic end, Benfica went from defending for their lives against relentless Los Blancos pressure to Real going down to nine men and the Benfica players being told they needed another goal.
Moment of the week - Keeper Trubin scores dramatic late goal
That brings us to what happened next. With the players aware they needed another goal and could no longer waste time, and instead needed to create something with the short time they had left, Mourinho threw everything at his former club.
A free-kick in the 98th minute was launched into the box by Fredrik Aursnes, and in one of the great moments in Champions League history, Ukrainian goalkeeper Anatoliy Trubin directed a bullet header into the corner to give Benfica the goal they needed.
That extraordinary moment lifted their goal difference above Marseille's and secured a play-off spot in the most extraordinary way. The scenes of delirium that followed on the pitch and on the touchline by Mourinho will never be forgotten.
For Trubin, it will likely be a memory that tops any saves he makes in his career, as he made a critical difference in the area of the pitch he is used to simply observing, watching on in hope like the supporters.
Last night, in his side's moment of need, Trubin came to his side's rescue, becoming the protagonist in a way he has never been before and may never be again.
Moments of such chaotic magic are so commonplace in this beautiful game and unique competition - we truly are spoilt.
