I don't disagree. If that was the sole issue then I'd be onboard but the duty of care is a red herring for me. Also, if it had come to nothing we wouldn't be talking about it. How often are 'slow' free kicks taken from the wrong place around the half-way line.
I've got no problem with either. Unlike the goalkeeper coming off his line, the taker has chosen to take his very average penalty with he GK doing that. And as for the second (yes, he should have stopped play) but 1) he wasn't kicked in the head as the foot made no contact with the head and 2)...
I’ve seen it four times from four angles in slow-mo and can’t decide - no problem at all with the referee not blowing for that!
Frankly I’m not even convinced it’s a yellow card (if it was out of the PA) - the ball as you say is more likely to go out than to the attacker’s feet so SPA is doubtful.
Nothing irritates me more than a referee putting his arm(s) up, shouting ‘advantage’ because of how proud of himself he is and then having to blow the whistle because no one has had a chance to collect the loose ball. It just looks like an inability to read the game to me.
