LOL at "fouled in the box". Mentioning Messi in the same paragraph as Luquinhas is ridiculous. Red might have been deserved and wouldn't have made an iota of difference.
I have seen messi get pks for miami because someone put a hand on him and he fell. If that is a pk, then luq getting tripped in the box is definitely a foul.
All I am asking for is consistency. If contact results on denying a person in the box a scoring opportunity without touching the ball then it should be a pk. Biases shouldn't be a factor and when it is the ref should be suspended and require to do trainings.
