As long as there's no proof if Qatar has bribed 8 players from Ecuador, I wouldn't believe since anyone can make an accusation from someone opinion or rumors. I think since Qatar is a strict country and didn't accept every other cultures, those people who hate Qatar create this drama in order to hurt Qatar and FIFA wouldn't choose Qatar again for the future World Cup's home.
I don't know if any such incident happened in 2022 FIFA World Cup. Because the football world cup is a world cup of competition that comes once in a few years. I haven't heard of any bribery crime in this world cup where any team will give money to any other team. It's a rumor I think.Because Qatar hosted the World Cup, other countries could make it a drama to blame Qatar.
So I will never accept it as true I think it is a rumour. It can create such dramas to spread a bad name by other parties. All of us will not listen to all these rumours.
