I agree with you. There were several facets to his game on Sunday that were far more alarming than a basic shot-stopping error which can happen to any goalkeeper, although these are becoming more common in his game.
More concerning for me was him passing the ball straight out to an opposing attacker twice, once in the first half to a lad about 25 yards from goal and once to Antonio inside the penalty area from a goal kick about 30 seconds into the second half; and how aerially weak he is, as you say, we got lucky he was apparently fouled for the one that resulted in a goal but there was a second instance a few minutes later where he stayed down feigning injury despite West Ham having possession in our penalty area, could easily have resulted in a second goal. Oh and probably most infuriating of all for me was him forcing Lindelof and Shaw to run 30/40 yards back to collect the ball multiple times late in the game when West Ham were just hoofing the ball clear, not only did it waste time it allowed them to regroup defensively.
