Agreed, but I also think Confed Cup should be taken more seriously than a rehearsal. On paper it's a good idea, 7 champions and the host fight it out for a trophy. It only can mean more quality matches than the world cup (other than the Oceania Champion).
It should be made for prestigious by FIFA. This match is one of the better international match in recent years. The quality of passing by Mexico in between the lines was great and Portugal as usual dangerous on the counter.
