Liverpool won the Premier League with relative ease last season, and so FSG's staggering summer of spending at Anfield must have struck quite the frisson of fear through the rest of the European game.
Though Arne Slot's side haven't been at their best across the opening fixtures of the season, they have claimed nine points from nine in the league, winning a tough match at St. James' Park before narrowly seeing off title rivals Arsenal after Dominik Szoboszlai's stunning free-kick.

The Reds haven't looked at their most fluent, but new number nine Hugo Ekitike has certainly started in fine fettle, three goals and an assist from his first four games.
Undroppable, right? However, the deadline-day acquisition of Newcastle United's Alexander Isak maybe stirs the pot a tad up top.
What Isak brings to Liverpool
Liverpool have two of the most dynamic strikers in the game in Isak and Ekitike, but both would fancy themselves at their most fluent and formidable when threatening from the centre.

Isak is the more clinical and refined man, to be sure, but he's also nearly three years Ekitike's senior.
Having two high-level centre-forwards isn't the worst problem for Slot to have, but he is going to need to consider ferrying one out to the left wing or pushing Liverpool toward a tactical transformation.
However, neither have Cody Gakpo's fluency as a left-sided forward.
And, of course, Liverpool have already sold an elite winger in Luis Diaz who could have been the perfect balancing force in the frontline.
Liverpool may regret selling Luis Diaz
Liverpool sold Diaz to Bayern Munich for £65.5m in July, with the German giants convincing the 28-year-old to join after FSG failed to agree terms on a new contract with the Reds winger.
He arrived from Porto as Jurgen Klopp's choice of replacement for Sadio Mane, and though he didn't quite live up to the same stratospheric heights, succeeded all the same.
Indeed, Klopp himself lauded his new arrival as a "top world level player" back in April 2022.

He leaves an integral part of an illustrious period in Liverpool's history, having scored 17 goals and supplied eight assists across all competitions last term, filling in at centre-forward on multiple occasions.
Though some questioned Diaz's output, he didn't do too badly, ranking fourth among all left wingers across Europe's top five leagues last year for goal contributions, and in what many would describe as the toughest division of the lot.

Given that Isak arrives at Liverpool with a wealth of prolific Premier League experience under his belt, he could have formed an incredible partnership with Diaz, who always balanced his output and ranked among the top 9% of positional peers in the Premier League last season for pass completion, keeping it crisp and opening up a strong supply line with the Sweden star.
The fact that Liverpool's player sales across the summer has left them with a smaller net spend than Arsenal perhaps underlines the suggestion that Diaz needn't have been sold.
Luis Diaz for Bayern Munich
The emergence of 17-year-old sensation Rio Ngumoha has tempered the Colombian's departure, but Diaz remains one of the most experienced and dynamic forwards in the business.
Equally, Florian Wirtz's struggles across his initial foray into the English game are a reminder that Diaz was pretty crucial in Slot's title-winning team, and he will be missed as the campaign progresses.
