There is not a goalkeeper that has lived that does not make mistakes.We can all pick and choose from videos.
It's worth remembering that Nery Castillo and Jo were brilliant on videos.
I fully expect that the number of Ederson errors well outnumber those of good saves. Of course, that almost certainly applies to most goalkeepers.
It's the silly, basic, and invariably avoidable errors that stand out with Ederson. He's not a great goalkeeper just because he makes a few good saves in a couple of games.
Ederson is a top keeper, you don't play for the best club side in the world if your not.
Ortega is a superb no2, probably far too good for that role but be careful what you wish in terms of Ederson, he is a huge part of this club on and off the field.
