I know it’s not what I said, but what I meant was, his mistakes haven't cost goals. I alluded to his faults in what I wrote. And it’s hard to drop a keeper when you can’t really point to a goal and say ‘that was their fault’. You’re right that if you keep making mistakes, you won’t continue to get lucky, but I do think he gets away with more than most, in part due to his reactions. The same is true for some of those double saves, his reactions and speed across the ground are excellent.
