This might not be too far off the mark (and I suspect Argentina will be similarly advantaged tomorrow).
My brother reminded me last night that he'd said at the start of the tournament that he felt the refs & linesmen would maybe have a big say in ensuring that the 'right' teams eventually got to the semis and ultimately the final, ie Brazil-Argentina. (Suits me - I took 9/2 after the group stages.)
If you think I have a suspicious mind, he said he wouldn't even have been surprised if the refs had been briefed accordingly before the tournament began. After all, this is a huge financial phenomenon for the host country, the continent and the organising body.
Would we really have been happy with a Belgium-Costa Rica final?
