You could see the hesitation and fear in Bravo last season, his confidence dropped so low he was trying to react to situations rather than taking control.
Ederson just looks completely in control, he's so quick off his line, so balanced and so agile he smothers the attackers and gives them no time to think. On top of that his reactions look as good as anyone I've ever seen, he's composed in possession and his passing short and long range is like Pirlo (slight exaggeration but for a keeper he's bloody good).
