I'm bumping this one after Karius' performances recently.
I think he has improved massively, and I'm impressed. This weekend stood out to me because he did that rare thing that top class goal keepers do: be bored and have f*ck all to do until one split second and pull out a world class save.
Mignolet was fine if we were under the kosh and had lots of saves to make, but he didn't have the concentration a keeper needs at a top club.
Karius is still very much auditioning for the rest of the season, but I think he's starting to show how good he really is.
I wonder if you are you still of this opinion after last nights performance?
Karius has benefited from not being tested in games but last night, his failings were on show again and no, he hasn't improved.
What game did you watch ?
What failings he had?
And it is a totally wrong statement if you said he has not being tested in recent games.
I can remember at least a few good saves in recent games:-
a PK save vs Spurs and off the line quickly to save an one-on-one in the same game
two very good saves againts Arnatuvic
one incredible saves against Diame shots
I believe his good saves are much more than above but I just highlighted some for your easy reference.
Besides, I think he had two good game versus Porto too (both away/home). He came off the line very quickly and cleared a lot of through balls.
