High foot vs headbutt consequences

[courty]

I understand the high foot dangerous olay punishment.

For example Roberts on Mateta= 6 game ban.
I don't understand why poleaxeing with forehead is not punished? For example David Luis flying in late and headbutting Raul Jimenez a few years back, consequences of which nearly killed Jimenez. No foul given, let alone a card or ban.
Considering red cards are issued for, forehead to forehead reactions, does anyone know why David Luis type headbutts (flying in late and endangering a player) are not deemed punishable?

I think you make a fair point. And technically, it could fall within excessive force and the ref could give a red. Arsenal recently conceded a pen away at Brighton for their player going for the ball with his head, getting a very slight touch, and then smashing head first into the Brighton player's head. It was a stonewall pen, just as it would have been going in with your feet, getting a touch on the ball, and the follow thru wiping out an opposing player. But Arteta described it as a clash of heads and was furious.

I think it's slightly different to the high foot, in so much as the aggressor is usually going to get just as badly hurt and the victim. Now intent, or lack of, should have no effect on the ref's decision, but it probably does. As it's bloody painful for the aggressor, it makes it obvious that it was accidental, so wrongly, it get treated more leniently.

Ref at fault for not correctly punishing the David Luis attack, Arteta very wrong re the assault on the Brighton player. IMHO the assault on Mateta was correctly punished, however it could easily have been a far worse result and that Millwall keeper could've been looking at way more serious repercussions as Mateta could have had his career ended that day. As a professional, that goalkeeper should never have followed through the way he did, even if it was unintentional.
