1. Qatar vs Ecuador match was done and Ecuador won for 2-0 against Qatar.
2. No evidence if Qatar bribed 8 players from Ecuador.
3. Why no one discuss if Saudi Arabia bribed Argentina players and Japan bribed Germany players?

There's nothing should be discussed anymore, why we need to discuss to a match that has been ended and the result goes wrong with people prediction. I ask to @OP to lock this thread and just focus to the next world cup match.
I do agree, but there were allegations though, and that's why it is being discussed whether this allegations are true or not.
And with Ecuador winning against the host, maybe they back up or something because they are in the limelight?
Those nations that you mentioned, we haven't heard anything though. But for the Qatari's they made a lot of noises in world cup not this one and has been discussed several pages back (like migrant workers dying and others).
