That space in goal is huge, much bigger than it appears on screen. I don't think he is particularly susceptible to medium range shots any more than most. That Jota goal was only 7 yards out and was more of a pass in than a hard shot, which is what he might have anticipated. The play had moved very quickly from side to side and he had to adjust his positioning a lot during the build up, he looked disappointed so maybe he thought he could have done better. A lot of goals are scored close to a keeper's body and from mishits and deflections, they might look easy to save, but you only have to stand in the goal and get somebody to shoot from 7 yards at you to appreciate how difficult it is.
