The age-old question 'who'd be a goalkeeper?' takes on new dimensions when it comes to evaluating the relative merits of the world's best shot-stoppers.
The ruling consensus is that Alisson Becker is the best in the world at the moment, and rightly so - it's incredibly rare to see a keeper who is elite at both distributing the ball and the fundamentals of goalkeeping. Within the specific framework of that all-conquering Liverpool side, there arguably wouldn't have been a contemporary player between the sticks that improved them more.
But what happens when things start to change, when the structure of the defence begins to melt away, when there is much more demanded of you as a goalkeeper? Well, ask Ederson.
Before Alisson's meteoric rise, the consensus previously was that Ederson was the standout goalkeeper in the Premier League, and perhaps the very best in the world. But, as even a casual Premier League fan could tell you, City in the last two years have become increasingly easier to get at.
In a team where the line always feels a smidge too high and where a well-weighted ball between the centre backs can wreak all kinds of havoc, compared to the formidable defence of the 100-point season, Ederson has found himself coming off his line much more often, and in much more perilous situations.
The result? His reputation has suffered, and who knows if the same will happen to Alisson with the post-Virgil van Dijk Liverpool now much more exposed to defensive breaches. The same certainly happened to Hugo Lloris.
Lloris had a reputation as one of the most consistent goalkeepers of the current era, long before he signed for Tottenham in the summer of 2012. But from about 2017 onwards, something had changed with the Frenchman, and fans very quickly sought to move on from him after a series of errors stretching over multiple seasons.
There were a multiplicity of factors which helped explain why Lloris lacked so much confidence over the last three years - from his legal issues in late 2018, to injury, to the shame of a blooper on the biggest stage of them all in the World Cup final.
But what was also happening from 2017 onwards was something far more meaningful at Tottenham - Mauricio Pochettino's maniacal press was beginning to exhaust itself, with chairman Daniel Levy refusing to sanction a desperately-needed overhaul of the defence.
Spurs' xGA (expected goals against) went from 33.2 in the 2017/18 season, where they clinched a creditable third-place finish, to 45.3 in 2018/19 (via FbRef), where they barely creaked their way to Champions League football.
You know what happened after that - that game against Bayern, Brighton running riot against a demoralised Spurs side, and Pochettino being told to pack his bags. Throughout, Lloris conceded some truly bizarre goals, the nadir being a defensive mix-up where Kieran Trippier was able to pass it into his own net at Stamford Bridge.
Watching some of Lloris' mistakes back, you can't help but feel that his own competence was not the sole factor at play, with a tired Spurs squad unable to protect their goalkeeper from playing himself into trouble from the Premier League's new crop of bright young things - his mistake to let Danny Ings in against Southampton last season, and indeed Trippier's own goal, show a goalkeeper who is uncomfortable with using both feet, but also a defence willing to put him under pressure.
The truth is that Lloris can be a bit of an awkward goalkeeper to fit into an uncoordinated defence. His outstanding reflexes are by far and away his greatest asset, and now that David De Gea is beginning to show some signs of wear and tear, quite possibly the best in the world.
But his issues with communication and distribution are married with a lack of strength and capability when it comes to commanding his area. In essence, you can't give him too much to think about.
However, something quite interesting has happened at Spurs, and it's something that has caused Lloris to bounce back from the limbo that Ederson and De Gea find themselves in - his role has, inadvertently or otherwise, been made much easier.
