Yeah i know that.
But Goslings arm was not in an "unnatural position". He was on the ground and using his arms to support himself in the push up position.
Commentators, fans, managers and referees alike seem to think that if the ball hits a players hand its instantly hand ball and is damn infuriating. MOTD might have reckoned it was a penalty but none actually explained why other than thinking that it hit his arm so was a penalty.
Gosling attempted to get his arm out of the way as opposed to putting it in the way. Ignore who it was, that was never worthy of being penalised because it wasn't against the laws of the game.
Its just tough luck on us that it might of been going in.
