It would also depend on how many goals are scored from each team. No doubt Mexico would be favorites because they could score more goals vs Saudi Arabia than Argentina can/will vs Poland. Still unbelievable that Saudi Arabia beat them.
I hope you're joking. Beating teams like Uruguay, Chile, Colombia, and Brazil is far bigger competition than Saudi Arabia or Mexico face in their confederations.
OK I'm starting to get triggered by these US commentators on Fox. This fuking idiot keeps calling Thiago Silva Casemiro, I have a feeling he has no clue who is Casemiro and who is Thiago Silva.
