Very Harsh penalty
It’s a definite penalty - but IMO I don’t see how it can be a red card. Someone will correct me I’m sure but he has made no attempt to tackle him
Isn't that the problem now because had Luiz tried to tackle him it would have been a penalty and a yellow, however, as the Law now stands, is it not the case that if you commit an offence other than tackling or attempting to get the ball then you receive a red card.
To be honest, after 56 years involved in the game at senior level, I no longer know just what is what isn't a penalty etc and I am usually good at keeping up with changes.
