he won't be replaced obviously and he has his advantages, but that "most suited for us" is bit of cliche we like repeating. In year or two us as we know us right now might not really be that us. Pep leaves and things change.
There are other keepers who are not as good as he is with his feet, but not that worse to think about them as not suited for us. Personally, I'd rather him to be less amazing with his feet, but better at shot stopping. Balanced qualities are always the best combination. Ter Stegen for ex. is the best example of keeper who I think would suit us better than Ederson. Not as good with feet, but still very good. And very, very good in classic goalkeeping. Overall, better keeper than Eddie. Won't be a popular opinion, but Allison is easily better overall goalkeeper than him too. Saves much more and he's not half bad in distribution too.
