Because other GK makes a mistake, we cannot criticize Ederson then?
Again, I am really happy of having Ederson and he's a top 3 GK for City, but he can be so much more than that. Let's compare De Gea and Ederson for example(I strongly prefer Ederson for us). There were 2 saves yesterday to Gabriel Jesus and KDB from De Gea that were incredible. Quick reflexes, explosive and quick feet. De Gea makes 1 of those every 2-3 matches. At the same time De Gea makes a horrible blunder every 2-3 matches. For a team like us, we need security in our GK and Ederson might be the least prone to blunder GK in the world. He is great and a perfect match for us.
BUT you will never see Ederson making impossible/really difficult saves consistently like other GK are capable. Whenever the opposition scores, I have never felt Ederson made a huge mistake, but several times I think he could've done better and that several other GK would save 30-40% of those while Ederson saves 0% of those. Again, I am really happy of having a great sweeper, a very secure GK, and his excellent passing ability, but he can be so much better.
He can be Neuer, and it's so obvious what his weaknesses are, that I am just amazed he hasn't improved them at all. His weaknesses are: 1v1, slow reflexes, and he is very slow and non-explosive whenever he stretches. The 1v1 are inexcusable: the way he stretches, the way he attacks can be easily improved with constant practice. Just check how Neuer or even Cortouis take on 1v1, and then compare to Ederson.
Slow reflexes and explosiveness/power in his legs/stretches can also be improved with proper training, especially when you have a slow/heavy GK like Ederson. There is room for improvement there. And that's what annoys me. He can truly be better, and turn into, not only a top 3 GK for us, but the best GK for any team.
