What Martial does is retaliation and a red, by the book, even though super soft. What Lamela does first is not hard enough to be deemed a hit I guess, so it’s a yellow. What he does afterwards is acting to be hurt, which is morally obnoxious, but not a punishable unfortunately. It should be, it always should have been, but we reward cowardness and faking injuries. If the punishment for real pain is a red, faking the same should be a red. Makes sense. Why didn’t the referee even check it?
Lamela should be ashamed of himself, but he won’t be. He is that kind of player, always has been. Fake hard man, then goes to the floor like he is 6 years old. Something Alli could have done, same with Guendouzi. Some will say he is smart, but no, doing something like that is always wrong. About time FA comes out and punish behavior which is against the message role modeles should send. You pretend to be hurt, here is a five game suspension. It’s the only way he will learn.
