Ah yes, he had a bad game in the derby so he's already shit, then there's a very unfortunate accident in the next where he was pretty much perfect. They just didn't see each other, they were following the ball, Ederson genuinely looked devastated when he realised what had happened. Yes he makes mistakes but he's proven himself as one of the best in the world, and the best in the world with ball at feet. Zack is good, but he's not Ederson. Muric is good, but he's not Ederson. Ederson is the keeper for the next few years unless something goes horribly wrong, which considering he got mauled in the face, sent off v Wolves, and always returns instantly after an injury... to me it suggests he's going absolutely nowhere.
