I would not be surprised at all if this indeed happened, but unfortunately this is one of those things in which we will have to watch the game and see the performance of Ecuador to determine if there is something fishy going on during the match, however if it is confirmed this happened it will be yet another stain on this world cup, which has been incredibly polemic from the very day that Qatar was selected as the host
If you are very familiar with the Ecuador team, you can easily spot if they are playing it for real or not.
But this kind of bribe may not come as a surprise, especially if they have money to spend and they want fame on top of that.
Qatar may have the goal to win no matter what, but such goal is not fair if they will resort to this kind of cheating and corruption.
I don't think they can celebrate it fully if they know what transpired just to get such coveted multi-million dollar trophy.
