This is my problem with fans and people who are shortsighted about what the player brings to the squad.  99 good and little mistakes they go about saying things they can't do if they was given the chance to do so.
The likes of Ederson,  Allison gave the defense they control confidence by using their legs very well to play the ballin the penalty box.
Onana isn't even bother he is already opened to the critics they can bring it coming.  Maguire did similar errors but wasn't faced rashly.
