The suggestion is that VAR did do its job and King was sent off for throwing his arm out at an opponent, regardless of whether he made contact or not.
I dont agree with that, but if thats the rule, then I guess we just need to accept that, much as we did with Oscars red card for a slip.
We could, and probably will just stay quiet about the play acting as most clubs and managers will instinctively protect their own player, and thats fine.
But if, as KMcAlpin suggests, you want to try and eradicate that sort of stuff from the game, someone needs to be brave and take a stand.
But you do need to be really careful and do it in a way that doesnt through your own player under the bus.
