Has a goal been scored? Soccer; The Rules of the Game Rule 16 - The Goal Kick A goal kick is a method of restarting play. A goal kick is awarded when the whole of the ball passes over the goal line, either on the ground or in the air, having last touched a player of the attacking team, and a goal is not scored in accordance with Law 10. A goal may be scored directly from a goal kick, but only against the opposing team. How is play restarted? If the ball had curved back and crossed over the end line, but not into the goal, how is play restarted?
It's a goal, I think. There doesn't seem to be a definitive answer, though.. some people think the ball is in play once it crosses out of the penalty area, some think that it needs to be touched to restart play. The 'procedure' section on the FIFA website says it's when it goes out of the penalty box. I can't tell if that's formally part of the rule or informal guidance. Further confusing things is the use of "attacking" and "opposing", as the team each term refers to flips halfway through the rule (or doesn't.. it's not clear!).
I think no goal was scored. After reading the Rules of the Game, here's my take: As to whether a goal was scored, the key seems to be in this sentence: A goal may be scored directly from a goal kick, but only against the opposing team. "Directly" means not having been touched a second time by a player. Also, the ball is in play after it passes directly out of the penalty area. That raises the matter of was the ball ever properly in play. For the sake of simplicity, let's say the ball did not pass out of the penalty area as it was turned by the wind. The ball was not in play. A goal was not scored and the goal kick would be retaken. Now let's look at the ball having passed out of the penalty area and in play. By all appearances, despite his trying to stop the ball, the goalkeeper did not touch the ball. So, the ball entered the goal directly. But as noted above, an own-goal cannot be scored directly on a goal kick. Had the goalkeeper touched the ball, the ball would have entered the goal indirectly and a goal would have been scored. Because the ball was last touched by the goalkeeper and then crossed the goal line and a goal was not scored, play would be restarted with a corner kick. Had the ball seen in the video crossed the goal line outside of the goal, again because it was last touched by the goalkeeper, play would be restarted with a corner kick.
The rule doesn't say that an own goal can't be scored on a goal kick, as it doesn't use that term. It's not clear what team is being referred to by "opposing team" in the rule there. Earlier in the rule, "attacking team" is used to mean the team that kicked the ball out. So one could believe that "opposing team" means the team now taking the goal kick. Or one could argue that the context flips because possession changes, and now the goal kicking team is "attacking". I lean towards the former because it is more consistent. It also makes more sense from a gameplay perspective. Because when you really think about it, why shouldn't you be able to own goal on a goal kick? If you're that dumb to kick it 30' in the air with gusting winds, you should suffer the consequences. Note that if the GK had touched the ball, it would have been an infraction because you can't be the first person to touch the ball after putting it in play (same goes for throw-ins.. you can't throw-in to yourself). The result would be an indirect free kick.
