Not sure taking into account closing down is really that useful. Sure if someone has blasted it into the top corner, but quite often a defender in the way obscures the shot too. It should be a simple case of "do you think he should have saved that?". For example, the Forest goal in the first game, he should save that. It doesn't matter that Bartley didn't close down like he should - it wasn't a rocket into the corner, Johnstone simply didn't move his feet enough. It was very similar to Butland's first the other night (for Johnstone's the ball is a little bit further away from him) and that was written off as a keeper error immediately.
