The moral of this week's Champions League story is that money talks, but only to a point: if the environment or confidence isn't there, then even the richest clubs can struggle. A prime example of this is Manchester City, who are on a horrid run despite possessing some of the world's best players and being one of football's richest clubs.
City may have had injury problems but they have more squad depth than most. Meanwhile, Atalanta are a side lacking in financial power and squad depth but are excelling. So what does this mean? Rotation and squad depth help but confidence is the cheat code to success in sport.
Star player - Conor Bradley
First and foremost let's address the elephant in the room - Alexis Mac Allister was the player of the match as Liverpool stunned holders Real Madrid on Wednesday evening. So how can another player from the same game be my player of the week?
It is a little thing called opinion. For me, Conor Bradley's handling of one of the world's best players Kylian Mbappe and clever one-touch assist for Mac Allister deserve massive plaudits. There were so many top performances from young talents in this matchday but the 21-year-old full-back's display was the most impressive.
The Northern Irish international has had to take his chances when they've come when competing for a place in the starting lineup with Trent Alexander-Arnold. However, when his chance came tonight on the grandest of stages, Bradley delivered a faultless performance and played a critical part in Liverpool's statement victory.
If you don't believe me then just check out his stats from the game. Bradley provided an assist, made nine recoveries, won seven ground duels and finished with an 85% pass accuracy. It was a faultless performance against Real's latest Galactico which included a committed two-footed slide tackle loved by supporters and critics alike.
Liverpool's talented youngster might be in the shadow of one of the world's best attacking full-backs but if Liverpool can't find a place for him then he will excel elsewhere - Bradley is far too talented not to.
Surprise package - Feyenoord
There are always so many contenders for this award because every matchday teams surprise me. Sometimes good teams who have been struggling suddenly kick into gear without warning or sometimes Manchester City get stunned by smaller opposition. I am sorry City fans but this is the second time one of your opponents has featured in this section and that speaks volumes about your troubles this campaign.
The strange thing about Tuesday night was that up until the 75th minute, City were heading towards the type of routine victory at the Etihad that they have become synonymous with during the early rounds of the Champions League. It felt like the end of their mini-crisis and a confidence-boosting victory ahead of a vital game against Liverpool this weekend. So the horror show that came in the final 15 minutes was the most shocking thing to happen during City's six-game winless run.
And whilst City were in many ways architects of their downfall with some awful individual errors, Feyenoord grabbed that opportunity and took their chances.
Ederson was at the heart of the problem for City and you could argue he could have done better for all three of Feyenoord's goals. However, the equalising goal in the 89th minute was inexcusable from a keeper with the pedigree and experience of the Brazilian.
Feyenoord played a long ball over the top of City's defence and whilst the situation was dangerous, Ederson seemed to react to the danger too late before completely mistiming a diving header ahead of the onrushing Igor Paixao and thus taking himself out of the game.
From there Feyenoord still had a lot to do and Paixao did well from a tight angle to whip in a cross for David Hancko who had an empty net awaiting him. It was a calamitous moment for one of the world's best keepers to complete a disastrous end to the game.
It could prove to be a valuable point for the Dutch outfit who move into 20th place and amongst the playoff positions. To have been 3-0 down against a side who in normal times would never surrender such a commanding lead will make it even sweeter for them.
As for City, they had the perfect opportunity to get themselves out of a rut but let it slip through their grasp and now their trip to Anfield this weekend looks all the more daunting.
Team of the week - Atalanta
With Manchester City struggling in the Champions League, an opening has emerged for automatic qualification into the last 16 which few would have expected before the competition started. Atalanta's sensational 6-1 thrashing away to Young Boys on Tuesday night has put them in a strong position to take full advantage of that opening; the side from Bergamo are in fifth place on 11 points and on course for a top-eight finish.
Atalanta have been one of Europe's most exciting sides for years but Gian Piero Gasperini is only now starting to earn his flowers in the media. They have gone from a great side on their day held back by inconsistent performances to genuine challengers in Serie A (they are currently one point off league leaders Napoli in second place) and Europe.
Their success in the Champions League before Tuesday had been based upon not conceding a goal but all their attacking talent (which has been their trademark domestically) was on full show in Bern.
It was a particularly good day for the on-fire Mateo Retegui who added a finely taken brace to the 12 league goals he's scored already this season.
The Italian striker has proven to be a brilliant piece of business since his summer move from Genoa and whilst Ademola Lookman remains the main man for Atalanta, Retegui is their greatest goal threat and has added a new dimension to their forward line.
Atalanta played some dazzling attacking football against Young Boys and they took their chances with ruthless efficiency. But it comes as no surprise - Gasperini's side have gone up a level this season. They are in unstoppable form and it would be naive to underestimate them any longer.
Moment of the week - Pep Guardiola's scars
The usually upbeat Pep Guardiola looked to be in anguish after his side's collapse against Feyenoord. Guardiola is known for speaking positively about his players and rival managers. It is rare to hear him talk in a defeatist tone but it feels like this run of six games without a victory is getting to him.
Not only did Guardiola bizarrely have red marks all over his head and his nose as he spoke to the media after the game but he seemed like a man despising his side's current situation. It's clear that he hates losing, and having just signed a new contract with the club, he will be working tirelessly behind the scenes to get City back to their best.
In one sense it feels like the Spanish coach could do with a break but I am sure he would argue the contrary and he'll want to focus on winning football games again.
A victory against league leaders Liverpool on Sunday would go some way towards healing some of those wounds. Defeat, however? That could break a man already on the edge.
