He has his problems as a keeper doesn't he? Distribution and command of his area. But in terms of shot stopping other than a few spells where he couldn't make a save, he has made tons of saves for the majority of his time there. You can argue that a lot of his saves come from his own poor distrubution and command of the box putting them in trouble in the first place, but a lot also come from the cretins in front of him through little fault of his own. I genuinely believe they might have been relegated at some stage if they had a far worse shot stopper in goal.
He's far from perfect but he's light years ahead of that Henderson fanny, who's as below average as the day is long.
I'd still have Ederson, Neuer, Alisson, Mendy, Donnarumma or Oblak (to name a few) over either though.
