They'd have to work out a formula for it, I suppose. I don't like the current one they use for deciding goals. If they were to take this one off Aguero, for example, it's only a goal, because of his touch & could possibly have gone in off the turf without the defender touching it, with a bit of spin on the ball, so therefore they can't be sure it's off target & it's his goal imo. Same with shots that bounce off a post or off the keeper & hit the post, then hit him & go in. The post should count as 'on target' in that situation imo, & the rest of he action all part of an attempted save. It''s not fair on either player, to call it an o.g imo. If the keeper catches it & drops it, fair enough, but if it hits the post, hits him on the head & goes in, it should not be an o.g. imo.
