This thread made me think, and I made a classification on what I've seen this season of al first choice goalkeepers.
Tier 1 - Worldclass
Alisson - What a signing. Still think his flair/style made him look a bit better than he actually is.
Tier 2 - Very good
Hugo Lloris - Good under Mourinho.
Ederson - Regressed a bit recently.
David de Gea - Regressed badly, very difficult to catagorize.
Tier 3 - Good
Nick Pope - Very decent, but still to be seen at a bigger club. How Burnley sets up, are perfect circumstances for him.
Bernd Leno - Not one of Arsenal problems.
Emiliano Martínez - Great. Still think Arsenal made the right decision.
Rui Patricio - Great. Probably outstanding tonight.
Édouard Mendy - Jury still out, but at the very least an upgrade on Kepa. Performances dipped a bit last few games. Likes a punch. Interesting to watch.
Tier 4 - Decent PL-goalkeepers
Vicente Guaita - The best of the rest for me.
Lukasz Fabianski - Badly missed last season when injured.
Alex McCarthy - Decent. Seems unbeatable two or three times a year.
Karl Darlow - Special mention to him, will probably keep his place when Dubravka returns.
Kasper Schmeichel - Regressed, think Leicester will look for an upgrade if form does not improve. Nevertheless, he was fantastic for them the last 5 years.
Tier 5 - Shows potential/not seen enough/some doubts/a problem
Alphonse Areola - What a diffence for Fulham compared to the shambles 2 seasons ago.
Illan Meslier - He likes to take risks, just like Leeds do. Will pay for that. A lot of potential though.
Sam Johnstone - Excellent games at Etihad and Anfield, at fault against Spurs. Will do well for them especially under Allardyce. Doesn't look like a modern goalkeeper, laks a bit of flair.
Matt Ryan - He's targeted by Potter. A bit too small for PL. Great reflexes and distribution, but vulnerable at crosses. Is he even still first choice?
Jordan Pickford - The less said the better. Difficult situation for Everton.
Tier 6
Aaron Ramsdale - Harsh as he was Bournemouths POTS last year. Difficult to be goalkeeper at a team without any confidence but made already a few mistakes. That £18,5m was massively overpaid. Will not be seen in PL the next few seasons.
