I mean I don't get this criticism at all. Yes, he pointed at that corner as a mind game against Saka, but why is he now actually held to that like he "had to" dive where he pointed? It was always a lottery anyway. Saka could have chosen the other corner as well, there is no rule to follow here just because Ederson tried to intimidate the striker. Isn't the whole mind game strategy to confuse the shot taker? He points to a corner, but he might dive the other way as well and the same goes for the shot taker, he may or may not decide to go for the indicated corner. If Ederson had dived where he pointed, but Saka decided to pick the other way and scored, would people still criticize Ederson "why did he dive where he pointed, wasn't it obvious enough that Saka wouldn't follow his bluf?". This is a lose-lose case for the keeper, he either saves the shot or he doesn't, the mind games played no role at all in this specific instance, because the shot taker and the keeper chose different corners.
