Unatural arm position ? i am still not convinced having watched thw highlights a few times. It looks like his arm was barely away from his body whats unatural about that. i can see the argument if it was at a 45 degree or more angle but it was not, it was ball to hand, no way for the player to avoid it, no intent, never stopped a goal. So for me never a pen, simple fact is the ref fecked up and cost us the win.
